Singapore-based software applications developer U2opia

2011-05-17T22:54:00.000-07:00

Singapore-based software applications developer U2opia Mobile has developed a new application for mobile phones that will allow them to access Facebook on all kind of handsets without paying for a data connection.

"We are using USSD technology, which will enable users to access Facebook without having a GPRS connection on their phones," said Sumesh Menon, the co-founder and CEO of U2Opia Mobile.

Unstructured Supplementary Data (USSD) is the technology used by telecom players to send alerts to their users that inform them about their balance at the end of call or for sending miss call alerts.

Menon mentioned that though the technology will not provide access to graphics, it will help users send and view updates on their friends' Facebook walls.

"It is like SMS and hence, the load on the network is negligible. We have built some commands through which a user can receive alerts on activity happening on his wall as well post an update," said Menon.

U2opia launched this application with Indian telecom major Bharti Airtel. While Airtel customers can update their Facebook status through this USSD service free of cost, Rs 1 per day will be applicable for accessing the full-feature application, which enables viewing news feeds, commenting on or liking news feed stories, posting on friends' walls, confirming friend requests, viewing notifications and finding as well as adding friends.

"In the Indian market scenario, where the penetration of smartphones is relatively low and the use of internet on mobiles is primarily limited to key cities, many users are excluded from accessing their Facebook accounts via mobile phones," said Shireesh Joshi, Bharti Airtel Director -- Marketing, Mobile Services, in a statement.

Airtel users can dial *325# and *fbk# for non-Qwerty mobile handsets to access Facebook without subscribing to data plans, the statement said.

"We look forward to bringing millions of Facebook users in India closer to their love for social networking by allowing them to access it anytime, anywhere on their Airtel-powered mobile phones," Joshi added.

CNC software also uses electronic memory

2010-12-14T07:24:00.000-08:00

CNC system software is what any CNC machine uses to create the operations within the machine. Generally it is considered to be the "intelligence" that governs the type of operation performance or the overall capacities of the machine. The software will be how the machine designs, cuts and operates the work that the operator programs into the computer.

CNC software also uses electronic memory modules where information is automatically stored inside the CNC machine. In some case this information cannot be changed and in others, through the use of temporary memory, it can be changed.

Generally speaking the computer is very important to the process of the CNC software because the computer numerical controls are usually outside the machine on a small or large keyboard. The computer is offline when it is performing the programming of parts and the computer controls the other parts that are necessary to create the product, depending on the type of CNC in use.

There are four basic software types that CNC uses:

Manual G Code Programming

Many of the larger commercial machines use and it is used for simple machine processes. The drawbacks of this type is that it takes a long time for someone to learn how to program G Codes and if you want to use more complicated machines, it is time consuming to learn how to use it. Because if these issues, many operators would rather not learn how to do this and

Offline CAM Programming

This type of programming can be done using a local PC and generally is available for larger machines as well as some of the smaller desktop CNC machines. This software can't be used without a PC at the front end aspects of the machine. This software is also difficult to learn and takes a long time to completely understand for many people.

Conversational Programming

This type of programming is a better type of software program for the use of CNC because it is intuitive, which means it is simple to learn by the average computer person and it is similar to the programming in regular PCs. The reason this type was developed was so that it could do both simple and complex parts without having to take so long to learn.

Windows Based Programming

Many CNC software programs are now Windows based which means it works through Windows XP or Windows VISTA. The operator can import CAM and CAD programs and it can import other types of software like dxf files depending on the type of machine being used.

Today all CNC programs go by a variety of names including MSHAK-CNC, ProtoTRAK or TRAK, and OpenCNC all with their unique way of approaching a CNC system.

Also the purpose of each software program is to make life easier for the operator and make the machine do what is required. The easier the software is for the operator to program, the more the machine will be used. The particular software has also been used with CAD and CAM systems which makes this easier for many operators.

CNC Software Trends in Woodworking

2010-12-14T07:23:00.001-08:00

Computer-Numerically Controlled (CNC), Computer-Aided Manufacturing (CAM) software is used in the woodworking industry to control a machine's movement, for instance a panel saw or a router. The instructions for controlling the machine are provided by a CAD module. This module is integrated with control software, or may exist as an independent application. In today's market high-end cabinet design packages are able to communicate with CNC machinery. Computerized manufacturing systems typically cost thousands of dollars. They are generally meant for industrial operations. Some cheaper systems have appeared in the market recently.

Besides mill work companies and high-volume furniture manufacturers, novices and master craftsmen have also embraced CNC technology. The number of possibilities and benefits that CNC provides cannot be ignored. Craftsmen have quickly realized that using CNC is crucial to ensure that a finished woodwork product is of the highest quality.

As a case in point, it is difficult to produce precise-fitting assemblies using conventional tools. However these can be easily created using CNC. Inlays, arches, and 3 Dimensional relief carvings can be cut easily and efficiently with the help of CNC technology. Time consuming designs or designs that are too complex to create with traditional woodworking tools can now be executed with a great degree of precision. Assemblies for knock-down furniture, for instance are very time consuming and require several templates and jigs. CNC replaces physical templates with digital versions which can be created in software. This provides the freedom to try out design and assemblies on a computer before actually cutting into the material.

It is easy to modify a design on the computer and adjust it to fit, or existing designs can be transformed into new products. Using the right software and hardware, existing 2D & 3D furniture parts can be converted to a digital format that is understood by CNC. The digital version of parts can then be transformed to produce a number of shapes and sizes for an original design. In this way a single furniture assembly becomes a complete furniture line!

Advantages of CNC in the Woodworking Market

CNC gives manufacturers the ability to quickly tailor products to suit a particular sector of the market thereby providing value-added services. For instance a manufacturer may produce a generic table as part of a furniture line selling at a given price point. By simply adding a 3D relief applique to the table with minimum effort the table can easily be sold for a premium. With a little bit of creativity, the manufacturer can easily provide customers with offerings that are elegant and unique, thereby adding to the company's bottom line.

The role of CNC in Crafts

Many people in crafts business are also taking advantage of the capabilities that CNC has to offer. They are using CNC to churn out high quality products, are able to produce better products for customers and are able to produce unique designs that their competitors cannot replicate by hand. Even if the craftsman uses CNC for shaping materials as the initial step or for unique decorative add-ons, the value added to the end product is immense. Also saving time during production leaves more time for creativity, so that the next product is even better than the last one.

Productivity gains through software integration

While CNC offers immense benefits on the production side, using automation software customer needs can be met more easily. The resulting cost reduction and increased productivity also reflects in a high return on investment, through increased profitability.

Such software integrates seamlessly with CNC, virtually eliminating manual operations. Further, the software is easy to learn, so manufacturers see rapid increases in productivity soon after implementation.

Besides automation, using software provides a significant advantage in tool pathing. By communicating with CAM the software automatically applies tool pathing. This significantly reduces the propensity for errors, and the inevitable time lags that come with the errors.

Analyzer Software of this kind can help provide information to make bar codes and labels also. On the labels a printed image of what the processed part will look like can be seen. In ad¬dition to the visual, there are dimensions as well. The advantage of this is that the wrong sized board will not be selected to make a part, and the CNC operator can validate what they are about to run through the machine, before any errors are made.

The move from manual to automation in the woodworking industry has helped tremendously in meeting customer expectations and improving profitability. The future looks even better. As more manufacturers embrace technology, the focus will shift from the actual production process to creating designs that are unique and have a distinct personality. A perfect win-win situation for the manufacturer and the customer.

Like I keep telling, it’s Google, “cnc at home” searchwords, and choose from a list of thousands!

Illustration 36A guy named V. Chan, at pathcom.com, created this drill-mill conversion

Software’s not a problem, you can find free software, cheap software, expensive software, you can even learn how to make your own CNC controlling software, what have you!

You can use your present PC to control it, use an old 386, buy the CNC, Computer, and all, but by now you’re just wondering:

“Yeah, right, but WHY DO I NEED A CNC MACHINE?”

Well, in theory, if you have one of those, you will never have to build a Prototype, just “draw” the pieces in some 3D program, have the CNC mill them out of metal blocks, or other material, and assemble the Prototype like as much as some IKEA furniture!

In my Prototype building experience, tough, NOTHING is that simple, something always needs some extra work, but hey, Industrial Precision pieces, just as you imagined them, now that’s something not to snare at!

Illustration 37 This guy, Tom Gootee, at fullnet.com, built a CNC machine from an Epson printer!

So go have some fun, be it building, buying it all ready to mill, converting it from a drill press, Google it, choose what’s right for you, could not be the one that suits your neighbor, the CNC world’s yours!

HEY! IT GETS BETTER!

Now there’s?Fab@home.org, and all your problem’s over!

These guys are into Fabricating, or CNC home manufacturing, or buildin’ your 3D stuff with a home made Robot.

And not only that, they help you MAKE YOUR OWN CNC MACHINE with only a fraction of the money you spend on Pro CNCs, but with a even more flexible machine! And you can even save more money, if you’ve got some old Printer around.

If you’re thinking you cannot do it, think again, ‘cos they teach every darn step, even WIRE CUTTING the right way, so there’s no excuse not to try!

Now that’s good news or what?

RepRap, another fabber

Here’s another Fabber, RepRap, notice the different steel rod approach, comes also with Software support, same as Fab@home…

Max’s, much more than a Little Robot shop

Max’s Little Robot shop, the title says…

But that’s not true: It’s a HUGE help for lots of projects you may have.

I’m just reading the tabs at the left of his page, Robots, Mechanical Fabbing, Injection Molding, the guy’s made a machine for it,

AND a download area!

There you’ll find lots of CAD files, don’t you just love the kewl CAD appearance…

Plus a Digital Electronics section that you have to see.

Be sure to give this Site a Look, you will learn a lot.

CNC simulation software cuts programming times

2009-07-24T21:28:00.001-07:00

CNC simulation software reduces prove out time for any NC machine tool program, by improving verification through visualising in real-time the whole machining operation - including workholding.

Reduced prove out time for any NC machine tool program through improved verification is the key productivity benefit of new SoftMachines CNC simulation software from simulation technology specialist, Applied Computing and Engineering.

The software allows NC programmers and operators to visualise in real-time the entire machining operation including tools, fixtures, palletisers and parts.

Soft Machines provides a cost-effective alternative to dry runs on the production floor.

It operates exactly like a real machine.

By executing G and M codes on simulated machines, tools, parts and fixtures, the software provides an accurate verification of the part program before it is run on the real machine.

"If a machine tool manufacturer can build it, Soft Machines can simulate it.

This frees the machine tool for production and eliminates the risk and disruption of equipment damage due to collisions," says Stewart Allinson, managing director, Applied Computing and Engineering.

Based on an exact representation of the user's machine tool, Soft Machines includes full machine kinematics, tool changers, optional material handling equipment and a machine controller emulator.

Tool assemblies can be loaded from existing databases or created from libraries of individual tools, adapters and tool holders.

Valuable productivity information - the CNC simulation software also provides valuable productivity information about the machining process.

Users are able to validate cycle time, feed rates and tool change routines.

Costly collisions can be detected and corrected before the actual machining process begins.

If an adjustment is necessary, the simulation routine can be stopped, corrected and then restarted from that point.

There is no need to repeat the entire program.

Easy to use - Soft Machines is intuitive and easy to use.

Tooling information is entered graphically and stored in tooling libraries.

Machine set-up is quick.

Parts and fixtures are imported into Soft Machines from existing CAD databases.

The machine code data requires no modification before it is loaded.

Once the program is executed, machining errors are automatically logged in a detailed error report.

Soft Machines is available on graphic workstations from Hewlett Packard, IBM, Silicon Graphics and Sun Microsystems.

Rebrand not skin deep

2009-07-22T04:36:00.000-07:00

Machinery visited Mills CNC in June to hear about the changes and rebranding since a management buyout last year. It's no mere superficial 'paint job', as he discoveredThe term 'rebrand' is sometimes met dismissively and viewed as a shallow change billed as something with more substance. There's no way of telling, unless you either see or experience the elements that sit behind it first hand. But there is substance behind the recent rebrand of 66-employee, £34 million turnover Mills Manufacturing Technology as Mills CNC, announced in January this year, with more than £100,000 cash invested to underpin it.

The change of name, explains sales and marketing director David Andrew, and one of four directors of the company which underwent a management buyout on 29 August last year, is because it more precisely reflects what the company does. "I often used to receive phone calls from potential suppliers asking us what it is we make, because the word 'manufacturing' in the company name implied that we were involved in manufacturing." In fact, Mills CNC was already the website name, and, as managing director Nick Frampton adds: "We were keen to stamp a new identity on the company to underline the change of management. We have a lot of ideas about how to take the company forward, plus it helped drive a step-change in company culture."

To stay at the visible level for a little longer, together with the name change has come a new logo, which, through the colours used, links the company directly with the machine tool colours of its principal, Doosan; and there's also a three-colour graphic comprised of the same colours and representing an 'M', in an Expressionist-type design – a consistent theme throughout branded staff clothing, marketing materials, and even posters and artwork, which are liberally distributed throughout the company's Leamington Spa, Warks, headquarters and showroom. Even company mobile phones display the three-colour logo, as do the umbrellas that protect customers as they travel between the company's two buildings.

Improved customer facilities in its showroom area take in an expanded reception/visitor coffee area on a mezzanine overlooking the showroom; extra discussion/break-out rooms at mezzanine and ground level, equipped with IT infrastructure; plus a central kitchen resource, complete with Sky TV, on the ground level.

The ground-level training room has seen the installation of an interactive white board, but is due for a complete refurbishment to bring it into line with the other, adjacent, high specification facilities. "We have what we believe to be the best facility in the UK machine tool industry, without being ostentatious about it," offers Mr Frampton.

Mori Seiki's NMV-3000 DCG

For Mori Seiki, orders for machine tools have fallen off slightly since 2007, but the company is optimistic and preparing for the economic upswing it predicts will happen sometime around mid 2010.

“Now is a very good time for us to think about the future and to invest in it,” said Dr. Masahiko Mori, CEO of Mori Seiki. “Companies that have been working hard up until the recession should have some reserve funds available for such investments and should be focusing on the upswing.”

For Mori Seiki, investing for the economic upswing includes a new state-ofthe- art research and development center, several new and innovative machine designs, a new machine control system, and new pallet system software.

Mori Seiki recently opened its 70,000-sq-ft Digital Technology Laboratory (DTL) in Davis, Calif. The facility is both environmentally and technologically advanced, and features a dedicated thermal isolation chamber, vibration dampening floors, solar power and space to house dozens of machine tools along with a showroom and offices.

The Digital Technology Laboratory does all the performance analysis of Mori Seiki machines.

The facility has acquired a Leadership in Energy and Environmental Design (LEEDS) Gold Certification. That means the building not only conserves energy and water, it improves the health and safety for both occupants and the community at large.

Adam Hansel, president of DTL, said the facility is located close to Western U.S. customers and serves as the company’s West Coast/Mountain area headquarters.

But, most important, DTL conducts all the analysis of Mori Seiki machines, even those designed at the company’s facilities in Japan.

One notable machine design DTL analyzed was the company’s soon-to-be-released NMV-1500 5-axis vertical machining center. As the smallest machine in a series, the NMV-1500 is geared for high-level processing of small, complex five-axis parts, such as impellers. In fact, the company has already received requests for the machine from shops striving to reduce their impeller machining cycle times to less than five minutes per impeller, which the machine has accomplished in testing.

To achieve the fastest possible partprocessing times, Mori Seiki equipped the NMV-1500 with a 40,000-rpm spindle and optimized the machine’s structure and kinematics. DTL conducted extensive analysis on the NMV-1500 to optimize the machine to the greatest degree possible, and testing focused mainly on the dynamics and rigidity of the machine’s design.

The NMV-1500 will have a pallet system or the option for gantry loading from the top. It is a box-in-box construction that includes an octagonal ram and direct-drive motors in all its rotary axes.

Two other machines resulting from Mori Seiki’s investment in the upswing are the NMV-3000 DCG and the NT-1000. The NMV-3000 is the latest in the company’s multi-axis vertical machining center lineup. It builds on the highly successful design of the NMV-5000 DCG by providing both high-precision machining and ease of use in a compact machine platform. Its X-axis travels 19.68 in. to accommodate workpieces weighing as much as 220 lb.

As the smallest in Mori Seiki’s integrated NT Series machines, the NT-1000 mill-turn is a compact multi-tasking machine with a footprint measuring only 58 sq-ft. The machine is well suited for high-precision medical workpieces.

Another noteworthy machine is Mori Seiki’s NM-1000 ultra-precision machine. Mainly because it was developed entirely by DTL engineers and uses diamond milling or scribing tools to machine part features accurately in micron ranges and generates nanometer- level surface finishes.

On yet another machine technology note, Mori Seiki is offering what’s known as Zero-Chip technology. To eliminate the chip disposal and cleanup issues associated with bridgetype machines, a Zero-Chip system evacuates chips by sucking them up through the machine’s spindle right where the metal cutting takes place.

As investments in controls and software, Mori Seiki developed the MAPPS IV control system and LPS-III cell controller software. LPS-III, with an endof- 2009 release date, will help shops manage their pallet pool systems better. Innovative functions of the software include material management, fixture management, capacity planning, and improved manned/unmanned operations. With this software, Mori Seiki’s goal is not only to increase a shop’s spindle utilization, but also the throughput of parts that can be assembled, shipped and invoiced.

Mori Seiki’s new MAPPS IV control features both a built-in CAM system and post processor. The built-in Esprit CAM system, from DP Technology, comes standard for high-volume machines, and Mori Seiki will pre-install a proven post processor.

Also new to the control is the addition of vertical soft keys on the operator control panel for better operability, and there’s a button for CAM. Operators can do CAM simulations right at the machine.

Other MAPPS IV features are MAPPS ACT (advanced communication technology), which requires only one Ethernet/ IP cable to run other devices such as robots, Mori-Net advanced monitoring system that turns a PC into a plant controller and allows for remote maintenance that’s connected to Mori Seiki’s service center, e-mail notifications of machine status, manuals and maintenance information within the control, and an internal/external monitoring function for handling internal and external cameras for machine monitoring.

New 3D High Speed Machining Enhancements to be Demonstrated MOORPARK

2009-03-17T02:54:00.000-07:00

"We have incorporated lots of new features plus enhancements across the
GibbsCAM product line, but the most significant are those they made for
Advanced 3D High Speed Machining" says Bill Gibbs, founder plus president of
Gibbs plus Associates. "All the additions are geared for ease of use and
productivity, with interface, interoperability, programming, verification and
machine simulation features that decrease programming plus prove-out time for
even the most complex machine-tool configurations."

a leading provider of integrated CAD/CAM solutions for the
toolmaking plus manufacturing industries, announced that Gibbs plus Associates,
developer of GibbsCAM(R), its software for programming CNC machine tools,
will demonstrate its latest version of GibbsCAM at WESTEC 2009, in exhibit
#3268, at the new york Convention Center in california, los angeles, from
March 30 - April 2, 2009.

Advanced 3D HSM (High Speed Machining) Enhancements - These offer
machining styles for smooth entries, exits plus cutting motions, with steep or
shallow angle limits, rest passes, tool-holder collision checking, and
options to alter cutting style, all applicable to multiple applications.

Significant capabilities were added to the lathe modules, but the
greatest enhancement for GibbsCAM 2009 was the addition of machining methods
for multi-surface hard milling plus high speed machining in SolidSurfacer(R),
to provide high quality surface finishes that reduce or eliminate polishing.

- Constant Step Over Cut - User-specified step distance drives this
routine to generate 3D passes with constant separation along a part's
surface, from the outside in, to achieve smooth finishes
through user-controlled steps.

- Flats Cut - This routine automatically recognizes plus machines flat
areas, using minimal distance retraction when moving from five section
of a work piece to another, avoiding work piece features while
minimizing non-cutting motion.

- Lace Cut - Like Constant Step, but cutting in a single direction, this
provides consistently smoother cuts. By using the toolpath filleting
option, also available within other HSM routines, users optimize
smoothness in cutting motion.

- Contour - For finishing plus semi-finishing passes, Contour computes
equal Z increments plus generates toolpaths at the various levels,
automatically providing neat transitions with smooth entries plus exits
from five level to the next.

- Intersections - This automatically identifies seams of a part surface
plus generates toolpath along those seams, following plus conforming to
the part's 3D shape. Additional offset passes generated from the
original seam pass provide a superior surface finish.

- Automatic Core Detection - For machining cores, this automated routine
machines from the outside in, always climb cutting to protect inserted
cutters. Toolpath direction changes automatically from inside to
outside when internal pockets are detected, minimizing need of full-
width or helical ramp-in cuts.

- Improved Pocketing - Like Automatic Core Detection, but specially
geared for cavities, it works from the center outward. By computing
equal Z increments on the model, it generates toolpaths for each level
plus removes large areas of material rapidly.

- Extensive New Lathe Features - These provide greater efficiency through
tool control, plus take advantage of newer high-tech cutting tools to
turn harder materials plus machine smoother surfaces. They include
advanced entries plus exits, entry feed rates, enhanced no-drag, clean-
up pass, multi-pass plunge roughing, notch ramp roughing, offset
contour plus tool edge path contour, threading entry plus tapping tools,
plus groove-tool deflection compensation.

MTM Enhancements to Sync Manager - New additions to Sync Mgr plus Op List
& new Op Mgr associativity make multi-task machining less hard plus more
efficient with the added flexibility.

Additional Enhancements - GibbsCAM 2009 incorporates multiple ease-of-use
& productivity enhancements, including faster toolpath simulation,
visualization features for multiple perspectives, hot keys for fast viewing
options in Cut Part Rendering, updated certification for Windows Vista and
Solid Edge v20, plus lots of additional interoperability plus interface features.

GibbsCAM 2009 shipped to domestic customers at the end of 2008, while the
international version, with localized documentation plus additional
enhancements for simultaneous 5-axis machining, will be shipping through the
first quarter of 2009.

What You Must Know About CNC Programming

2009-03-13T23:15:00.001-07:00

To successfully cut the metal and do various processes in manufacturing, we need to use CNC programming since they are a most effective way of doing this work. Many hobbyists are using CNC programming to produce woodworking, metals and foam objects. It is possible to quickly fabricate and manufacture parts we need without hassle, because of the CNC.

Using computer for certain types of operations is what CNC is - to be more exact, a computer numerical control. This is a process that can be applied to lathe, router, foam cutters and laser machines; it can also be applied to mini versions of these types of machines.

Actually, there are two main categories in which the CNC program will be placed, a continuous path positioning category or a point to point category. Usually a computer can execute both types of programming depending on the sophistication of the software program being used. This means that the operator must understand both processes in order to run the machine.

And now I will present you with the explantaion of the categories stated above:

We use point to point positioning category in computer numerical control if we need to tapp, drill, bore or punch. This is a process used to position from one point to another when the machine process is being done. To tell it more directly, it will go from one position to another, no matter how many are there, and it will keep working until the complete process is finished.

In case we use milling or lathe machine, then we need to use continuous path positioning category, which is needed for contouring. It’s just a different name that we use for the same category. Since the cutting tool will move constantly through all points, without stopping, the piece will be completed in one move. This means that the operator has to be able to program the machine so that it continues on several axes at a time and simultaneously.

Types of Manufacturing Software

2008-09-21T22:31:00.001-07:00

Currently, a large variety of software is available to the manufacturing industry. The software helps the industry to improve a multitude of manufacturing as well as organizational functions.

Firstly, software has been developed to control and monitor machines used in manufacture of products. Each type of machinery works in a different way and therefore requires a specifically designed software program.

Computer-aided manufacturing (CAM) is software used to generate the codes to give instruction to CNC machines to enable them to form shapes designed in a computer-aided (CAD) system. This helps the modern manufacturing plants to meet their high volume high accuracy production requirements.This also simplifies the job of the person who is watching over the machines and makes it significantly less strainous.

The second important function of a software programs is to facilitate better control on financial and personnel management. The software for this purpose is usually applicable to all types of industries and institutions. Nevertheless, minor changes may be necessary to tailor the general software for a particular industry or institution.

Thirdly software programs are able to streamline and improve management functions within the manufacturing industry. Because computers control the machines, time and motion studies of various manufacturing operations, and stages can be more easily undertaken. It is possible to stay up-dated and effectively control the status of critical items, such as raw materials, inventory and order status, goods in-process status, finished goods inventory, and delivery status. Planning and scheduling software enables the industry to monitor manufacturing activity, through time and action calendars that track key milestone events and create alerts. Activities such as packing and labeling can be controlled, by getting real time status on exact quantity of pieces packed for different orders, per quantity, per color, and per size, to reduce possible back charges.

CRP Launches Windform PS

2008-05-11T23:51:00.000-07:00

Vol 16, Issue 2
CRP has been recognised as a leader in the use of Rapid Casting for motor sport applications throughout the world. These efforts have now yielded a breakthrough in this arena — Windform PS.

Windform PS is a new polystyrene-based material able to produce complex investment casting patterns. The sintered patterns are porous in order to allow wax infiltration, making them easy to handle and finish.

Windform PS patterns can undergo the typical rapid casting procedure, including autoclaves and flash firing steps, low-temperature furnaces and vacuum plaster casting methods.

Compared with other polystyrene materials available on the market, Windform has:

# Improved surface quality and details reproduction.
# Less “curling” effect on the first layers.
# Very low ash content suitable for highly reactive alloys, such as titanium, aluminium, magnesium, steel and nickel-based alloys.

It is particularly suited for the foundry and RP markets since the main applications are:

# Complex investment casting patterns.
# Casting with highly reactive alloys, in addition to typical cast alloys.

The casting structure is formed of an aggregate of grains, or polyhedral crystallites, which produce isotropy compensation, a solid metal that is an isotropic. Thanks to isotropy, FEM calculations are very close to the real behaviour of the part.

Rapid Casting with laser-sintered patterns also allows complete shape conception freedom, needing no even supports and reducing undercut and tool path problems during CNC machining. It also allows for perfect optimization of the project to the working conditions, making it possible to create a product along its mechanical stress axes, and to obtain a perfect reproduction of all details of the RP pattern, with tolerances and surface finishing of fully machined parts that are of a very high quality.

FS Precision Tech is an investment casting foundry. They cast complex castings for CRP in both Titanium and Steel. Greg Gregory, Technical Director of FSPT said “I find that Windform PS material works well with our process and produces castings of equal or greater quality than the standard material. FSPT would recommend using Windform PS as the rapid prototype material for any casting house”.

CRP Technology produces Windform PS powder and distributes the material worldwide. Windform PS ships in 10 kg stackable metal drums that are certified (CoC attached), as is standard with all Windform products. The recommended wax is a standard 100% paraffin wax (with melting point of about 54°C) and infiltration is for about 10” @ 70°C.

CRP continues to improve the Rapid Casting process because the company knows what its customers need. The adopted slogan is, “At 300 km/h, quality isn't optional, it's your life.” Their belief is that failure is far more expensive than quality.

ERP software avoids duplication

2008-05-11T23:48:00.000-07:00

ERP software automatically develops documentation, from quotation to order right through to delivery note and invoice, and avoids an older system's duplication said a tooling manufacturer.

Within the nacelle of a wind turbine there are sets of bearings in the drive-train that allow the transfer of the rotation of the blades via a gearbox back to the generator There is also a large bearing fitted at the base of each blade where it is attached to the hub

These allow the pitch of the blade to be trimmed according to wind conditions, to maximise energy extraction and stop any torque overload during high winds.

Such has been the uptake in this renewable source of energy that globally there is a shortage of the large diameter special bearings required.

As a supplier to the companies that manufacture these bearings, Sheffield, UK-based Pen Cutting Tools is constantly under pressure to deliver.

Established in 1963, the company's managing director, John Shaw, explained: "Many of the bearing suppliers are investing heavily to support renewable energy projects, with wind and wave power generation being the most favourable at present.

There is currently a world shortage of the large bearings typically used in wind turbine equipment.

These bearings can go up to a staggering 4m in diameter and there is currently a three-year wait for any large diameter bearings".

To keep pace with demands Pen Cutting Tools has expanded its own production facilities building on from traditional milling, turning and grinding the company now has high-speed milling, 5-axis wire erosion and die sinking machines.

All of these processes are used to finish parts from engineering plastics, tungsten carbide, diamond and hardened steel.

And, it's not just the capital equipment that has seen investment to improve productivity.

* ERP avoids duplicity - one of the company's key purchases, said Shaw, has been its Enterprise Resource Planning (ERP) manufacturing software bought from Seiki Systems.

Shaw said that the Seiki Systems ERP system replaced a 15 year old manufacturing system.

Shaw explained: "We had a new IT hardware system installed with a networked server followed by the Seiki Systems software." Apparently, Pen Cutting Tools was one of the first companies in the UK to install the Seiki Systems ERP software.

A full training package was provided to help the company get up to speed as quickly as possible.

According to Shaw the amount of time saved in the front office by the software is incredible.

He said: "From the data I input, the software automatically develops documentation in a logical way, from quotation to order right through to delivery note and invoice.

It avoids the duplication that was taking place with our old system, keeping the whole process as streamlined as possible".

As the company runs mainly small batches, the quoting process can be a bottle-neck for the 25-strong company, with 22 of the staff working in production on the shopfloor.

However, the search facility within the software allows similar jobs to be found and essential information, such as margins, hours booked and so on, viewed before any new quotes are provided.

Shaw added: "Searching the many jobs that have been loaded on the system, within a couple of minutes I can get a good feel for the process time required for a job.

Then I only need to update the material price.

It requires far less running around to track down the information".

He continued: "The margin figure was set up for us by Seiki Systems.

After we told them how we worked it out, they duplicated that in the system.

It helps to highlight any jobs that were taken on at too low a price and allows you to quote more accurately the next time".

* Quick turnround - although accurately costing the wide variety of tooling required to produce tightly tolerance bearings is vital to the company's profitability, a quick turnaround is also important.

The lead time from design to production of a bearing used to take four to five months.

The target now is to do it in eight to 10 weeks, including prototyping and tooling for production.

This is not easy when the material specified can have a three to five week lead time.

To avoid any material-specific delays, consignment stocks of wear parts and consumable tooling is held at the customer or by Pen Cutting Tools.

This is charged when the stock is used and has helped the company win a number of contracts - running as a Kanban system for solid carbide shoes, hot forging tools and so on.

A significant amount of raw materials is also held.

Shaw said that he was aware that the company did not use every aspect of the ERP software but he said it's very flexible and the elements which are used provide more than enough benefits.

He exampled: "I can now track our turnover as invoices are issued, on an hourly basis if I want, this is something we have never been able to do".

Shaw continued: "Previously it would have been an end of week updated figure.

The dynamic data allows us to alter what we are doing to stay on top of the business.

It also keeps historical data so that we can track peaks and troughs to help us address issues that occur throughout the year".

* Scheduling - Pen Cutting Tools will be looking at Seiki Systems scheduling system soon to help manage the machine loading on the shopfloor.

And, if it is as flexible as the ERP software and able to fall in-line with how the company has to work with its customers it may well be the next investment the company makes.

Shaw concluded: "From our point of view it has been an excellent investment, support has been first class.

Seiki Systems makes sure we run smoothly and any issues we have with the system are address remotely, which saves time.".

Software Module facilitates high speed machining

2008-02-18T21:54:00.001-08:00

Expanding 3D milling functionality, SolidCAM2007 R11 includes high-speed machining module for molds, tools, dies, and complex 3D parts. Module offers machining and linking strategies for generating optimum roughing and finishing CNC high-speed tool paths. Program smoothes paths of both cutting moves and retracts wherever possible to keep continuous machine tool motion. All machining passes operations support point reduction and arc fitting for gouge-free tool path.

Powerful and market-proven HSM Module fully integrated in SolidWorks

August 29, 2006 - SolidCAM, the Gold-certified Integrated CAM-Engine for SolidWorks, today announced that it will present SolidCAM2007 R11 to American and European audiences at the IMTS (Chicago/USA) and AMB (Stuttgart/Germany) tradeshows. With this release, SolidCAM is further expanding its 3D Milling functionality by providing a very powerful and market-proven high-speed machining module (HSM) for molds, tools and dies, and complex 3D Parts. The HSM module offers unique machining and linking strategies for generating optimum roughing and finishing CNC high-speed toolpaths. With demands for ever-shorter lead and production times, lower costs and improved quality, High Speed Machining (HSM) is a must in today's machine shops.

SolidCAM's HSM Module smooths the paths of both cutting moves and retracts wherever possible to keep a more continuous machine tool motion - an essential requirement for maintaining higher feedrates and eliminating dwelling. Retracts to high Z levels are kept to a minimum; angled where possible, smoothed by arcs, retracts do not go any higher than necessary - thus minimizing aircutting and reducing machining time. All machining passes operations support enhanced point reduction and arc fitting. The result is an efficient, high quality and gouge-free tool path. This translates to increased surface quality, less wear on your cutters, and a longer life for your machine tools.

Rest machining can be calculated even in areas where the final cutter is smaller than the curvature of the part. A succession of rest finishing toolpaths from a series of successively smaller cutters can be easily created, even on very large jobs. All operations feature tool holder collision checking and work with tapered tools.

According to SolidCAM's managing director, Dr. Emil Somekh, the new HSM module expands the 3D machining capabilities of SolidCAM, allowing users to generate complex NC programs for different types of High-Speed cutting machines. "Efficient machine utilization and excellent surface quality will be the benefits for our users. Being fully integrated into the SolidWorks platform, we can now offer a complete CAD/CAM solution for the Mold, Tool and Die market and other high-end applications." The new SolidCAM2007 R11 will be available to SolidCAM customers at the end of the third quarter.

CNC Systems

2008-02-18T21:53:00.000-08:00

A Computer: The computer is used to draw the design. However, the design is only a picture and the CNC machine cannot use this to manufacture the product. The computer software must also convert the drawing into numbers (coordinates) that the CNC machine can use when it starts to cut and shape the material. The computer is used to input the design. Technical software such as CAD software is used to draw the design. The computer connects to the interface.

An Interface: A computer can't be directly connected to a CNC machine. It's connected to an interface. This converts the signals from the computer to a form the CNC machine understands. The signals are in the form of digital signals when they are sent to the CNC machine.

CNC Machine: (A lathe, mill, cutter, drill system). The signals from the interface control the motors on the CNC machine. The signals determine the way the vice moves. The vice moves in three directions X, Y and Z. (Horizontally, vertically and depth). The signals also control the speed of the cutting tool.

Control software expands possibilities

2008-02-18T21:49:00.002-08:00

Rick Pedraza, Managing Editor, Digital Media

IS THE MARKET for general motion control products nears a projected $7 billion annually, new developments in machine control software are allowing machine builders to interface with more different hardware devices. At the heart of this increase (the market was more than $5 billion last year and is projected to reach nearly $7 billion in 2010) is the demand for control software for Ethernet-based networks.

According to a recent report by ARC Advisory Group, Ethernet-based networks tuned for motion control are opening the door to high-end application performance by enabling levels of speed, capacity, and determinism unthinkable just a few years ago.

“The growing tendency to use motion control software has created a demand for platforms that include features such as human machine interface, logic and motion control, and communications,” states ARC’s report. It notes that the advent of PC-based motion control systems that rely on software has made users aware of the need for open architectures.

Our roundup shows the emergence of a new generation of motion control software products that merge the best features of PLC and PC-based controllers. Many PC-based software platforms in our round-up offer functions that are more convenient than those in legacy systems, but transition costs can be very high, the study adds. This has been a major deterrent to users in the industrial automation sector because so many are already heavily invested in older technology.

However, proprietary control systems that are less vulnerable to virus breakdowns and have reduced dependence on hardware are gaining in market share as the recent trend toward integrating vision and motion systems software increases its adoption in applications requiring high-level precision.

Several new improvements include soft-CNC solutions that offer a complete environment with HMI, multiple-axis motion control, and PLC tasks on one platform without dedicated motion-control boards. Other advances include adding modularized instructions that perform simple to complex ladder logic, which reduces processes to a simple programming block with fill-in-the-blank parameters.

More of the automation suites below enable redundancy, tunneling, recipe management, SNMP, UA, and SAP connectivity. Machine builders now use newer motion software technology to increase machinery throughput by servicing machinery modules offline without process interruption. Motors, drives and I/O modules can be removed and reinstalled to the live network individually or in groups for off-line service or upgrades.

Working with cnc software

2008-02-18T21:49:00.001-08:00

Good cnc software is essential for your machine. As the software tells your machines what to do and where to do it, so that your unit can execute the pattern you have input perfectly every time. There are many different vendors of cnc software. Most cnc machines come preloaded with software designed specifically for that machine. However, some users may find that the one that comes with their machines is too limiting, or that it conflicts with their CAD programe or operating system.

Fortunately aftermarket cnc programs are available, and these products allow users to customize their machine tools to suit their specifications.

Special software allows users to input their own programs in one platform, rather than having to use several programs to produce a single pattern. With cnc programming software, users can write their code in one place, and will most often be able to produce patterns without having to write programs in another format.cnc software center The advantage of this flexibility lies in time savings, as well as avoiding the possibility of data loss or incompatibility issues as you transfer data from one program to another.

One of the most exciting aftermarket products for CNC routers is 3D software. With 3D cnc software, the user would be allowed to produce precisely carved 3D patterns, which can be especially useful for signs or other wall hangings. One great feature of 3D cnc software is the ability to import images from other sources. Most software accepts .gif and .jpg images, and it is amazing how well these images are reproduced in startling 3D. With a tool like 3D cnc software in your workshop you can produce beautiful and intricate carvings and engravings, which can then be painted with realistic colours to make them come alive.

If your machine came with a good suite of software you may be unwilling to pay for aftermarket software. There are many free cnc software programs on the Internet, and these can help you try new programs without having to make a major purchase. Some of these free cnc software programs are demonstration versions, while others are fully featured programs with little or no limitations.

An Introduction to CAM Software

2008-02-18T21:48:00.004-08:00

CNC milling machines have of course been developed based on conventional milling machines, where the tool is moved through the material by operating a hand wheel for each of the available axes (X, Y, Z, ...). The basis of adding NC (Numerical Control) is very simple: replace the hand wheel by a positioning motor and add some electronics (the NC controller) to control the position. Nowadays many conversion kits are available to perform such operation.

The first NC controllers were very simple: no user-interface, just an option to read the tool-positions from a punched tape. Very soon new controllers were introduced, including a simple computer with a special-purpose keyboard and a display. The operator now could enter the sequence of movements to make (the NC program) on the controller, which was called CNC (Computerized Numerical Control). In some cases a tape puncher / reader still was available for external storage.

Next step was of course to use a PC for external storage, communicating with the CNC controller via a serial cable. This allowed the operator to conveniently sit at his desk to enter a new NC program, while at the same time the CNC machine was executing a previous job. Do note that for most desktop machines the situation is a bit different, as here a PC is used for the CNC controller (much cheaper than a special purpose control computer).

In the situation just described the operator enters the complete NC program on the computer, using a plain editor like Notepad or a special purpose NC editor. Each movement has to be separately entered, like "G01X10Y20Z30" for "Machine in a straight line from the current position to position (10,20,30)". This is of course very labor intensive, and this is where CAM software comes in to 'automatically' generate NC program files.

2. The position of CAM Software in the process.

In order to manufacture a part, nowadays typically three different software programs are used (see the illustration above):
- First the CAD software to make the design of the part
- Next the CAM software to calculate the toolpaths based on the design, compensating for the cutter's geometry, adding feedrate and spindle commands, etc
- Third the control software to read the toolpaths and let the machine actually move along these paths.
This subdivision of tasks by three different programs is the same for both 2D and 3D applications.

The Control software comes with the milling machine, while in contrast the CAD and the CAM software have to be bought separately. In case an NC controller with built in special purpose computer is used, the Control software is integrated. In case of a PC the Control software has to be installed, still it "belongs" to the machine as the machine cannot function without the Control software. Do note that many lowcost CNC machines are delivered with MS DOS based Control software, as the realtime control needed for machining is difficult to program under Windows.

Communication between the three programs is done using files. From CAD to CAM the design is transferred using a file format for geometry data exchange. For instance file types like IGES, STL and STEP for 3D, DXF for both 2D and 3D, and Postscript and HPGL for 2D applications. These are standard formats that in most (!) cases can be used without any special configuring needed. Much more can be said about these file types.

Communication from CAD to Control software is done using NC program files, for which many formats do exist. In most cases the format will be a (minor) variation on the ISO / DIN G-code format. G-code is supposed to be a standard, however in practice each manufacturer chooses a bit different implementation. In other cases a proprietary format is used. So for this communication the CAM software has to fine tune its output in order to meet the requirements of the NC controller used. This fine tuning is done by the Postprocessor.

The Postprocessor is the part of the CAM software that translates the toolpath data into the correct file format when saving (in fact an export filter). This functionality is the same as used in the (Windows) device driver that comes with any printer, to translate the wordprocessor's output to the format required by that printer. In many current CAM systems the postprocessor can be configured by the user, making it easy to connect to any new machine. This in contrast to the older CAM packages where the user has to pay (much) money to the supplier to order a new postprocessor.

I some specific situations one of the three programs just described (CAD-CAM-Control) may be omitted. For instance some machines can be used without control software (like the small Roland models, where a plain "print" command is sufficient to start the machine). Or in some setups a plot file (or even a 2D DXF file) from the CAD system can be immediately sent to the control software, skipping the CAM step. Still it makes sense to distinguish the three basic steps, for a clear picture of the process involved.

3. Types of CAM software.

Many different CAM software packages are available, showing large differences in price. It is a very difficult job to get a clear view about each system's capabilities and it's price/performance ratio. The CAM software comparison table on this website(CAD/CAM Software Comparison Table)is a great help, still only doing some real-life testing gives good evaluation information. To give some guidelines for choosing, two basic categorizations can be made.

A clear difference is present between CAM software for 2D and for 3D applications. With 2D is meant that the CAM system imports a 2D drawing file and calculates a toolpath with all movements taking place on a constant Z-level. Obviously several toolpaths on different Z-levels can be combined to create a 3D result, which is called 2.5 D machining (note that more definitions of the notion 2.5D do exist). In that case to user has to enter the correct Z-level to be used for each toolpath. A 3D CAM system in contrast imports a full 3D CAD model and calculates toolpaths to create a 3D result. Note that in this case also toolpaths on constant Z-level may be used (waterline machining), however these are automatically generated. Many CAM packages do offer both 2D and 3D, however still have their clearly recognizable foundation in one of both fields.

A second distinction is between simple and high-end CAM software. The high-end stuff is meant for professional toolmakers, who know about all possible milling parameters, want to be able to control any parameter for an optimum result, and are willing to pay for that. These extra high-end parameters do include options like
- support for a fourth axis, or for full 5 axis machining
- optimization for High Speed machining (constant tool load)
- special sequences for approaching and leaving the geometry (lead-ins)
- automatic stepover calculation
- a wide choice of machining strategies, like parallel, spiral, radial, pencil tracing, flat surface recognition, offset machining, plunge milling and automatic smoothing of almost vertical surfaces.
- automatic detection and removal of rest material
- management of undercuts
- rendered machining simulations.
The more simple programs offer less options, and are thus both cheaper and easier to use.

4. A few more Remarks.

The word "NC Program" can be used in two senses, which can be quite confusing when communicating about CAM. In this article it is used for the 'File that contains all toolpath information', exported by the CAM system and imported by the Control software. As the word "Program" in most cases means Software, sometimes the word "NC program" is used for a 'Program to calculate NC data', so for the CAM software. Be aware of possible confusions.

The capabilities of your machine must of course match the requirements of the CAM software. One requirement should be checked, as some older CNC machines do not offer this: 3D line interpolation. This means the possibility to travel from point A to point B in a straight line in full 3D. This is not easy, as all three axes will have to keep up a different speed. Some machines are only capable of straight lines involving 2 axes (2D line interpolation).

A second important machine capability is on-line machining: the capability to handle large NC program files directly from the computer's hard disk. This involves some handshaking between the PC and the controller, as in most cases the data transfer will be faster than the actual machining. No big deal: any simple printer can do so. However be aware that many CNC machines cannot: they have been designed for NC programs that are completely entered by hand, so consider a 100 Kb NC program file as very large. For CAM this is not large: it is easy to create 10 Mb NC programs, or even larger. Those older machines require the complete NC program file to be transferred before the machining can start, limiting the file size to the (say) 256 Kb of available internal memory. The option of on-line machining is also called drip-feed, or DNC (for Direct Numerical Control).

Software provides CNC machine simulation and optimization

2008-02-18T21:48:00.003-08:00

Based on single-piece frame cast from polymer composite material, Genesis(TM) 130H can be installed and re-located with no special lifting equipment. Direct-drive spindle motors eliminate need for mechanical adjustments, while cam-driven double gripper loader enables part load/unload times of 2 sec. Work area is isolated from machine frame to minimize thermal expansion from contact with hot chips. Stainless steel cutting chamber with steep inclination ensures that chips fall clear of work area.

Rochester, New York, February 16, 2006-- Gleason's new Genesis(TM) 130H CNC Vertical Hobbing Machine features a revolutionary new design that optimizes dry machining, significantly reduces floor space requirements and greatly improves cycle times.

The 130H Hobber is the first in a new family of gear production equipment from Gleason called Genesis(TM). All of the Genesis machines share a common platform: a single-piece frame cast from an advanced polymer composite material, which can be made faster, more accurately and with inherently more rigidity than conventional cast-iron assemblies. This common platform design also ensures a small, compact machine footprint and enables the user to install and re-locate the machine with no special lifting equipment or special foundations.

While the 130H Hobber can accommodate wet cutting processes, it is particularly well-suited for dry machining. The work area is completely isolated from the machine frame to minimize thermal expansion from contact with hot chips, and a stainless steel cutting chamber with steep inclination ensures that chips fall completely clear of the work area.

The 130H Hobber is equipped with an innovative new mechanical cam-driven double gripper loader fully integrated into the machine. As a result, costly non-productive time can be cut to a minimum, with part load/unload times as short as two seconds.

Unlike conventional hobbing machines, the Genesis 130H utilizes a new, patent-pending hob drive system to eliminate complicated mechanical and hydraulic clamping systems. Instead a simple "D-Drive" system enables the spindle to transmit more torque, with less runout, and at the same time accommodate the use of larger diameter hobs for greater performance and longer tool life.

The 130H also features direct-drive spindle motors, which further reduces setup and machining times by eliminating the need for mechanical adjustments and change gears. Higher acceleration/deceleration rates and increased torque, combined with faster axis motions reduce non-cutting time between cycles and increase overall productivity during machining.

Other significant features include:

o An Easy Access Service Module that consolidates hydraulics, lubrication and pneumatics into one location.

o Optional on-board chamfering and deburring capability.

o Availability of the latest SIEMENS or FANUC controls and the latest Gleason software running in a true Windows[R] environment.

o The chip conveyor may be located from either the side or rear of the machine to meet any cell/system arrangement.

Gleason Corporation is a world leader in the development, manufacture and sale of gear production machinery and related equipment. The Company's products are used by customers in automotive, truck, aircraft, agriculture, construction, power tool and marine industries and by a diverse set of customers serving various industrial equipment markets. Gleason has manufacturing operations in Rochester, New York; Rockford, Illinois; Dayton, Ohio; Plymouth, England; Munich and Ludwigsburg, Germany; Bangalore; India, Studen, Switzerland; and Harbin, China and has sales and service offices throughout the North and South America, Europe and in the Asia-Pacific region.

Tapping into new Technology

2008-02-18T21:48:00.001-08:00

The maturing of CNC machine tools, growth in CNC synchronous tapping, high pressure coolant through spindles and modern tap holders, when combined with application-specific tap geometries and coatings have all contributed to advances in the production of internal screw threads. Thread milling technology is also contributing to a rethinking of the production of an internal screw thread.

Making an internal screw thread faster, with better quality and reduced cost is always a challenge, easily met with today's technologies. Not long ago Emuge suggested running taps in cast iron at 35 to 50 sfm. Today tapping speeds of 100 to 250 sfm are easily achieved. In mild steel we formerly suggested 25 to 80 sfm. Today speeds easily reach 100 to 300 sfm. For good measure solid carbide thread mills can produce the same thread at 260 to 820 sfm.

Better machines, better results

CNC machines of today are faster, more accurate and simpler to operate and program than those of just a few years ago. The ability to accelerate, stop and accelerate in reverse quickly, is vital to tapping threads efficiently. Machine tool technology has developed more stable machines, providing the best environment for producing internal threads. High-pressure coolant through the spindle is important to maximize threading speed, thread quality and tool life.

Developing taps to be faster, better and last longer takes a continued engineering effort that does not stop at the factory laboratories. Emuge engineers continually visit customers and work first hand with their toolholding and threading applications. In both tapping and thread milling, understanding and using correct CNC programming is essential. The data contained in the accompanying table shows a typical time comparison between full-speed tapping and thread milling.

Looking at the accompanying time comparison, the thread milling cutter with countersink in this case produced the fastest time...even though the Thriller had lower tool cycle times. This is due to the fact that the thread mill had four flutes while the Thriller only has two flutes. Had this been a smaller size such as M6, the full speed tap and Thriller would have been better choices.

This is a faster way of threading than to tap at a conventional speed of 65 sfm. Understanding the benefit of full-speed threading is the beginning to improving productivity and generating real cost savings.

To be fair, not every company has the luxury of the latest CNC machining center to take advantage of the latest tooling developments. However, this should not prevent them from producing threads faster, with better quality and at less cost per hole. These companies should examine the threading process in the same manner we do for developing new taps for modern CNC applications and consider the following steps to tap selection:

Consider the material and material hardness being tapped and select a tap specifically designed for that application. All manufacturers of taps now offer a wide variety of taps for most all material being tapped.
Consider the hole configuration. If the hole is blind or part way into a through hole, then choose a spiral-fluted tap that will extract the chips out of the top of the hole. If the threads are completely through the hole then choose a spiral pointed tap that will efficiently push the chips through the bottom of the hole.
Always choose a surface coating such as TiN, TiCN, CrN, TiAlN and so on, for the tap for threading. The surface coatings extend tap life, reduce cutting pressure, aid in chip removal and allow for faster cutting speeds.
Consider investing in new tap holders. Tap holders built today are of much better quality than those of just a few years back. If you do not want to invest in new holders then at the very least do preventative maintenance on the holders, lubricate them and make sure the tension/compression features work smoothly. Many older holders become bound up from coolant residue and many just wear out.

In all threading applications, performance can be improved by adding coolant through the tap. This feature, especially with high pressure (700 psi), adds a new dimension making internal screw threads. Taps can now be run much faster without the fear of generating too much heat. Tapping in the horizontal plain is even more important as coolant from external flows has a hard time reaching the cutting area of a tap in the bottom of a hole.

Automation For Information

2008-02-18T21:47:00.001-08:00

“Making chips” is a common-enough expression for describing production metalworking, but chips are not the only byproduct of production. Another byproduct is information. In addition to making chips, you’re also making data. And today, it’s possible to put that data to use.
Here are examples of the kinds of data that are out there. At any given moment, your machine tool is either cutting or it’s not. The machine is in service or it’s not. And if the machine is cutting, then a particular tool is loaded in the spindle, and the spindle is experiencing a particular load.
All of this information has always existed, but in the past it was difficult to gather. The information was available only through observation, only by someone standing at the control. But now, CNC networking capability makes it possible to gather information remotely, transfer information with ease, and analyze information from throughout the plant on a single screen. Because it can simplify so much of the work of empowering and overseeing the manufacturing process, a shopfloor network might prove to be the most powerful productivity tool in the plant.
In fact, for the manufacturer that uses information well, the very nature of overall equipment effectiveness (see Overall Equipment Effectiveness: The Formula For Finding Your Plant’s Hidden Potential) might undergo a fundamental change. Moving, monitoring and managing the shop’s data can help to improve all three OEE components—availability, performance and quality. After that, the network makes it possible to track these components, continuously recalculating them from the most recent data. With this current information, OEE is no longer a static statistic, but instead it becomes a precise, real-time measure of the plant’s performance—a measure that everyone in the plant can keep an eye on. And when this value is less than it should be, the plant’s automatic data gathering can make it easy to see where the problem’s root cause can be found.
What follows are some examples of information-related improvements.
Availability: Information Coming And Going
If a manufacturer’s availability is low, then by definition, breakdown and setup losses are the problems that need to be addressed. Information coming from the machine can address the first sort of problem, while information sent to the machine addresses the second.
In the event of a breakdown, the first important piece of information is the existence of the problem. If this information has to travel by word of mouth, then response time will be slow. A better solution is to enable the CNC network to send a pager alarm that alerts a member of the maintenance staff at once. The technician can then use the same network to ensure that the response to that problem is efficient. Through remote access to the machine’s operation and maintenance screens, the technician can diagnose the problem at a distance, and arrive at the problem with potential solutions in hand.
To reduce setup losses, a high speed network connection can ensure that part programs and tool, work and fixture offsets all arrive at the machine as they are needed. The operator doesn’t have to enter any of this information by hand, and may not even have to call it up by hand, either. A part program delivered in this way is the most up-to-date version in the plant. Tool data delivered in this way can include the history of a particular tool’s cutting life so far, even if the tool has moved from machine to machine throughout the shop.
Performance: Seeing Where The Cycle Is Slow
Improving performance is where the data generated at the CNC become the most useful. From moment to moment, every machine has a particular status that the CNC is able to report. The machine is cutting, the machine is idle, the machine is cutting at a reduced rate because of feedrate override and so forth. By sampling the data continuously, and by analyzing the data within software that is designed to provide a graphical, big-picture view of the information, a plant’s engineers and managers can immediately see problem areas that otherwise might never have been apparent.
For example, perhaps one machine tool routinely runs the same part number more slowly than other machines just like it. Why is that? Or the operator may routinely have to resort to feedrate override during a particular portion of a feedrate override during a particular portion of a given program. What is wrong with the program in that area? Or, the time between pieces for a given part number may seem to vary widely. What is it about loading that particular part that is causing different operators to encounter different levels of difficulty?
Graphic displays of the day-by-day performance data not only reveal problems such as these, but they also reveal the relative magnitudes of all of the competing trouble areas. Engineering personnel can see exactly where they should focus their attention, by seeing where the greatest amounts of potential production capacity are going underused.
Quality: What Went Wrong And Why
That performance data collected from the CNCs can also be coupled to quality data, revealing an even bigger view of how well the plant is doing.
The most basic quality information is the number of good parts as a percentage of the total parts produced. Because this percentage is the definition of the quality score in OEE, tracking just this much information makes it possible to keep the OEE value up to date.
However, if a little more information can also be collected—such as which machines produced which parts, along with a description of every rejected part using basic numerical codes for common errors—then this information can start to be applied toward increasing the quality yield. The information gets incorporated into the same graphical view as the performance data, allowing the most common and serious quality problems to be visually identified.
Many plants already do something like this. Quality is one area where manufacturers tend to be accustomed to tracking and analyzing data—as in statistical process control. And SPC can continue to be one of the ways that quality data are used. OEE and automated information management simply take the same appreciation for the value of information that already exists in the quality area, and they extend this appreciation to the data being generated throughout production.
How Do I Do This?
To take control of shopfloor information, a manufacturer does not need to have the most modern CNCs. Nor does the manufacturer need to have CNCs that all come from the same company. Technology from a solutions-provider such as GE Fanuc can make it possible to upgrade many, many different CNCs (old and new, from various companies) so that they can all share a common network. That same solutions-provider can also supply the software capable of capturing, organizing and graphically presenting the data.
Perhaps the most striking thing about implementing a system such as this is how little the implementation costs compared to the potential return. Instead of purchasing new capacity or new machinery, the plant realizes a potentially larger amount of capacity that formerly was going to waste.
OEE makes the return apparent. Because this number describes how much of the manufacturer’s potential capacity is generating profit, an increase in OEE indicates how much additional profit is coming in. Just multiply your sales × your gross margin × the increase in OEE percentage that you were able to achieve. The result is the additional profit.
Time is money. Information automation not only saves time, but also reveals where the time is being wasted. Using the calculation above, a manufacturer can see just how valuable it is to recapture some of this resource.

Software Becomes The Backbone Of CNC Machining

2008-02-18T21:46:00.002-08:00

Penco Precision (Fontana, California), founded in 1975, is a medium-sized CNC precision engineering job shop with 17 CNC machines installed. The company specializes in tight tolerance batch work for clients in the aerospace, instrumentation, medical and computer peripheral supply sectors. Batch quantities go from a few to several hundred, with a lot falling between five and 25 parts. Tolerances are held as tight as 0.0002 inch on turned diameters up to 0.75 inch and positional tolerances to 0.001 inch. Occasionally, a true position (TP) feature is required when milling, which then demands precise and careful handling.

Since Penco acquired its first CNC machine in 1984, the plant has grown to eight CNC lathes and nine machining centers. Turning capacity up to 6 inches diameter by 15 inches length and machining center capacity up to 24 inches by 36 inches by 18 inches is now available. Machines include a CNC sliding head lathe specifically for slender shaft work and one lathe with C-axis capability. Other facilities include a 3D coordinate-measuring machine and a computerized job scheduling system, while the in-house quality systems are ISO 9002 compliant.

Penco used to develop part programs using fairly basic methods, according to Glynn Pennington, president. "The only off-line facility that we had was a simple computer-based text editor," he says. "The pressure to upgrade came from two directions. First, we were being asked to machine more complicated radius and blend features; second, as the number of machines increased so did the programming workload, which was increased due to the trend for short batch demand."

Stone Working Technologies and Water Cutting Systems

2008-02-18T21:46:00.001-08:00

Computerised stone cutting technology has given the stone industry an ability to cut designs with accuracy in a short span of time. It has put the stone industry into a bright millennium to come. Over a period of time this system can be more economical than existing one. This system can tailor the stone to any design' to suit the taste of customers worldwide. Computer technology continue to advance,allowing the stone industry to implement the latest technology Of precision and optimal production, Computerized designs (CAD), computer Assisted manufacturing (CAM), computer Numerically controlled (CNC) and other Computer controlled systems to integrate working machines for very good result in designing and mass production.

According to top stone designers from the USA, designs can be planned by computer And transferred to the machine to fabricate, Enabling the multiple finished products to be An exact duplicate of the original design. Thing can be done with human hands they can not do the same cutting several times like machine in a quick span of time with utmost precision. In the USA, Orlanofl, has employed computerized Fabrication technology ever since it began Production in January 1996 using the flow Jet system . According to Jonathan Smiga, a Leading stone designer in the USA, Intrasia Is a new method used to cut natural stone In complex pattern without any cracks.

Cost Control

Computer technology enable stone designers to repeat designs with precise specification. Use of such a technology can ultimately lower the cost for customers. Speed, together with ability for mass production are the two main benefits of computerised machinery which also reduces cost. For example, due to the CNC technology, the Burlington Stone Industry has the ability for mass production of vanities, kitchen counter tops, intricate tops and circular works such as flowing skirting, table tops, counter tops and legs. The use of such a technology can also cut down on labour force thus reducing the production cost.

Stone Products

With the application of computerized technology, various designs can be accomplished. The Pellegrini Wire Saw is used for profiling as well as removing large amount of materials with a single profile cut, while the Omag is used for its milling capacity and accuracy for repeated laser digitised objects. In addition to CAD, CAM and CNC systems, Scan Technologies of Denmark has developed a system for three dimensional work which has just been introduced in the USA. Jhinson Atelier is one of the main users who nicknamed it as CAROSO (Computer aided restoration of stone objects). According to Claus Nealson of Scan Technologies, this system allows the user to scan a picture into the computer. The resulting computer file is a three dimensional model that mirrors the geometry of the object. This system is used to measure and memorise models so that the used can manipulate design and execute it in stone. CAROSO, the three dimensional system is mainly used by companies that are making sculptures, signs, funeral art such as head stones and other artistic designs .A portable version of this machine has been put to use at the Cathedral of Milan, Italy. According to Nealsen, a stone designer this portable scanner does scanning and enables the user to work with stones at a particular place. Designs can then be down-loaded on to computerized stone working equipment so that the pieces tan be replicated and replaced.

Adding the CAD component to the CNC machine makes it more difficult to operate.The CAD and CNC staff must work together to operate the machine. On the other hand, CAROSO system is easier to learn than the CAD or CAM systems. Virtually, all the fabricators who have invested in computerised technology have acknowledged a learning curve. Sometimes, these machines run slowly while experimenting and documenting with different types of stones. The granites are not similar. Black, green and red are the most difficult stones to cut and polish. CAD, CAM; CNC and other computer systems are constantly advancing and this development is very important to the stone industry. Companies in stone industry which are lagging behind in adopting computer technology should immediately adopt the same in order to meet the challenges of ever growing and changing demand for stones worldwide.

Waterjet Cutting System

Waterjet cutting is one of the sophisticated system developed Germany, USA and other countries to cut granite rocks to any shape with high precision, both in the quarries as well as in the processing units. This system can produce any type or pattern of processed granite products. The system can be utilized for granite material which is otherwise considered as waste material in India. India has vast resources of such granite material for producing value added products. Waterjet cutting technology, when utilized for making monuments, markers and memorials,work load and wastage are considerably reduced. In fact, we can make all such products with high precision and less wastage of material. This technology is undoubtedly and indisputably the most suited for granite industry. By adopting this system, the industry can take up all kinds of installations, fabrication and construction work throughout the world, especially in the USA. Besides construction work, this method can be adopted to cut different shapes and sizes of granite material for manufacturing lanterns, vases, curios, wall clocks' and other precision oriented engineering products. By adopting this method, waste material can be converted into value added products.

Later, the entire methods and models can be computerized to have quick access, catering to the need and taste of buyers throughout the world. India can hold a very important position in the world market in processing granite products due to its unique colors, textures, patterns and vast resources of different varieties of granites. Eventually, it is up to the Indian government, quarry owners and processing industries to adopt computer technology and the Water Jet Cutting System and reap its benefits. In the future, these two will prove versatile and economical in cutting and processing the most beautiful Indian granites for the global market.

Software helps small machine shop become lean manufacturer

2008-02-18T21:45:00.004-08:00

Three years after starting his own company, A & F Machining and Manufacturing (Englewood, Colorado), Alex Farkas was faced with a dilemma. His CNC machine shop, which produces parts for customers in the high-tech, automotive, agricultural, food and entertainment industries, had grown from one employee in 1997 to 13 in 2000. Mr. Farkas thought that having more manpower was going to make his business successful, yet adding more employees was causing the company to lose money. "I had to stop the bleeding without hiring more employees," he says.

One possible solution was to hire a shop supervisor to manage the scheduling of jobs, machines and employees. However, Mr. Farkas realized that the investment would not be cost effective at the time. It was suggested that shop management software might help his situation, so he started to explore what was available. He looked into several different software packages, but he noticed that many of them were either too expensive or too complicated for a small machine shop.

After considerable exploration, he decided to try Realtrac (Irvine, California). "It appeared to be cut and dry, yet it provided the essential shopfloor control capabilities I was looking for," Mr. Farkas explains. "Moreover, the initial investment required was reasonable."

He soon found out that although using shop software required learning many new concepts, it was clear that the unproductive time of shop employees was diminishing. By the end of the third week, Mr. Farkas realized that the software was more powerful than he anticipated, and that it had the potential to help provide the control of shop operations that the company so badly needed. He soon was able to extract himself from the daily production picture so that jobs could run smoothly without his help.

Since implementing the software, productivity and efficiency at the company have increased substantially. For example, it used to take Mr. Farkas 2 to 4 hours to prepare an estimate. Using Realtrac, the average time to prepare an estimate is about 30 minutes. Once a job is accepted, an estimate can be turned into a job with a router/process plan in less than a minute. As an alternative, a router for a previous job can be duplicated in seconds.

Also, communications with shop employees have improved. Without being told, a machine operator can quickly see what has to be done next. The operator is also able to determine similarities in machine setups and suggest alternative schedules in order to minimize downtime. As a result, employees are becoming more involved in the day-to-day operations, and they feel they are contributing to the success of the company.

The software's employee time summary reports have also helped the company identify critical areas for improvements in a straightforward manner.

After implementing the software, the company's volume of business started to increase, and employees began to believe in the system as they saw the potential for an increase in their personal earnings. Mr. Farkas says that before implementing Realtrac, he was trying to solve problems after they occurred. Now he can anticipate problems and be a proactive manager.

Mr. Farkas believes that in today's manufacturing environment, the small machine shop can survive only by striving to be a "lean and mean manufacturer. "The Realtrac shop management system, along with good organization and management of employees, has helped A&F to achieve this goal.

Mach 2006 showcases CNC software

2008-02-18T21:45:00.003-08:00

CGTech will showcase Vericut v6 CNC simulation and optimisation software on stand 5760, hall five at Mach 2006 from 15th to 19th May at Birmingham's NEC. Vericut 6.0 has features to increase the ability of CNC manufacturing engineers to simulate the entire CNC machining process to increase manufacturing efficiency. It simulates CNC machining to detect errors, collisions or areas of inefficiency, and lets NC programmers eliminate prove-outs, reduce errors and increase CNC machining efficiency.

The software reduces scrap loss and rework and optimises NC program feed rates to reduce cycle times, increase cutter life and produce higher quality surface finishes.

Post processed G-code programs provide a virtual machining environment.

CNC machine tools simulated include those from Mazak, Makino, Matsuura, Hermle, DMG, Dixi, Mori Seiki and Chiron.

Vericut runs standalone but can be integrated with CAM systems such as Catia v5, Unigraphics, PTC, Mastercam and Edgecam.

Version 6.0 can synchronise an unlimited number of machine channels or machines with multiple synchronised CNC controls.

Its virtual machine is organised into multiple subsystems that are all synchronised to run together seamlessly.

Users can process multiple setups using the project tree.

Each setup has its own CNC machine, fixtures, tools, NC programs and simulation settings.

The cut stock can move from setup to setup, with automatic orientation.

Once a user selects the CNC machine configuration, the stock, fixture and design component information is attached to the machine ready to simulate the entire set of machining operations.

The Optipath NC program optimisation module has been made easier to implement with a redesigned tool manager; tooling data is now stored inside the tool manager.

This simplifies the implementation and lets multiple tools reference one Optipath record.

The new-tool assembly wizard lets the user create a new milling tool in one panel by answering a few questions.

The model export option has been enhanced in version 6.0 to allow export of native Catia v5, Acis Sat and Step models.

Model export creates CAD models from the Vericut in-process cut model generated by simulating an NC program.

In version 6.0, Model Export outputs features where possible and synthetic features when individual features are not possible or desirable, such as scalloped created by a ball end mill.

Using the simulated in-process feature geometry to create a CNC program containing probe motion makes on-machine in-process inspection practical.

It allows the creation of inspection sequence reports in HTML or PDF format for use by machine operators or quality control staff.

Working with cnc software

2008-02-18T21:45:00.001-08:00

Good cnc software is essential for your machine. As the software tells your machines what to do and where to do it, so that your unit can execute the pattern you have input perfectly every time. There are many different vendors of cnc software. Most cnc machines come preloaded with software designed specifically for that machine. However, some users may find that the one that comes with their machines is too limiting, or that it conflicts with their CAD programe or operating system.

Fortunately aftermarket cnc programs are available, and these products allow users to customize their machine tools to suit their specifications.

Special software allows users to input their own programs in one platform, rather than having to use several programs to produce a single pattern. With cnc programming software, users can write their code in one place, and will most often be able to produce patterns without having to write programs in another format.cnc software center The advantage of this flexibilitylies in time savings, as well as avoiding the possibility of data loss or incompatibility issues as you transfer data from one program to another.

One of the most exciting aftermarket products for CNC routers is 3D software. With 3D cnc software, the user would be allowed to produce precisely carved 3D patterns, which can be especially useful for signs or other wall hangings. One great feature of 3D cnc software is the ability to import images from other sources. Most software accepts .gif and .jpg images, and it is amazing how well these images are reproduced in startling 3D. With a tool like 3D cnc software in your workshop you can produce beautiful and intricate carvings and engravings, which can then be painted with realistic colours to make them come alive.

If your machine came with a good suite of software you may be unwilling to pay for aftermarket software. There are many free cnc software programs on the Internet, and these can help you try new programs without having to make a major purchase. Some of these free cnc software programs are demonstration versions, while others are fully featured programs with little or no limitations.

Open CNC software adds choices

2008-02-18T21:44:00.001-08:00

He has continued to offer MDSI's innovative software motion technology and OpenCNC software CNC to manufacturing companies worldwide. Fall engineered MDSI's move to globalization with the company's acquisition by Tecumseh Products Company in April, 2002.

Manufacturing Engineering: What is open CNC software?

Fall: It's an unbundled software computer numerical control (CNC) that is independent of any hardware and includes all of the following in software as an integral part of the control: HMI, interpolation, servo algorithms, RS-274D parser, PID and PID tuning tools, soft PLC, a defined and well-structured API, and a data server that can push data across a network. It runs on standard office-grade or industrial PCs.

ME: Why should a company use open CNC software?

Fall: The great advantage of an unbundled all-software CNC is that it gets you on a different technology curve, a software technology curve. What this means is that you can continuously improve the productivity of your machines by installing new versions of the software-a matter of simply loading a new CD-without being forced to do complete and expensive control retrofits and hardware-- swapping that is the hallmark of traditional proprietary CNCs. Another reason for moving to an unbundled software CNC is to reduce the life-cycle costs of machine tools. With a renewable software control, users avoid the steep increases in costs that occur in traditional hardware systems when hardware becomes obsolete, or when improvements can only be made by throwing out the old and starting over. An unbundled software CNC can change and grow along with your manufacturing assets and processes. Also, the performance of off-theshelf PCs continues to improve while the price drops, and unbundled software CNCs allow you to take advantage of this-once again, without incurring significant hardware costs. Finally, an unbundled software CNC benefits the user because it provides realtime data that manufacturers can use to continuously monitor and improve their processes.

ME: Can one program fit every type of machine tool?

Fall: The dream of every manufacturer is to have a common control across a broad range of machine tools. An unbundled all-software CNC can provide this capability. We designed reconfigurability into the OpenCNC product from the beginning. This capacity to reconfigure the existing control across a broad range of machine tools, axes, and job streams was recognized by the US Patent Office awarding MDSI a patent. When one program can fit every type of machine tool, manufacturers can move operators freely from one machine to another and training costs are decreased.

ME: Does it completely eliminate the control software that came with the machine tool's controller?

Fall: Yes it does. The machine tool becomes a device on a network, just like a printer is now in your office network. Device drivers pertinent to each machine tool come with the software, not with the hardware on the machine.

ME: What kind of computer equipment is needed?

Fall: Unbundled software CNCs run on standard PCs and use standard communications cards to talk to the servos and I/O.

ME: How difficult is it to run these types of programs?

Fall: With the advent of graphical user interfaces, unbundled software CNCs are more intuitive and easier to learn than traditional hardware-based CNCs and user interfaces. Furthermore, upgrades to the unbundled software CNC don't require retraining in the dramatic way control retrofits of hardware controls do.

Historically, with proprietary hardware CNCs, multiple generations of different kinds of hardware controls across multiple kinds of machine tools have maximized costs, isolated each element, and hamstrung an enterprise's ability to change and adapt to new technology. Unbundled software CNCs that include HMI, interpolation, servo algorithms, RS-274D parser, PID and PID tuning tools, soft PLC, a defined and wellstructured API, and a data server that can push data across a network offer the first true way out of the Balkanization of the traditional factory.

Software aids in wheel design for CNC tools and grinders

2008-02-18T21:43:00.001-08:00

Suited for X Class range of CNC tools and cutter grinders, Wheel Editor v27 includes key hole punch software for creation of punch geometries from library of shapes. Software also enables creation of customized contours and punches with concave and convex shapes. Additional features include Delta-C R850 drill point sharpening function and Profile Pivot Editor function to optimize feedrate.

Melbourne - ANCA has recently released version 27 for their X Class range of CNC Tools and Cutter Grinders. This version is packed with new innovative features that make the performance of an ANCA machine more efficient, provide significantly extended flexibility and enhance the possible spectrum of applications.

The two main new features with version 27 are the addition of Key Hole Punch software and Delta-C R850 Drill Point. This increases the applications on version 27 to more industries. The Keyhole Punch software allows creation of punch geometries from a library of shapes and also allows creation of customised contours. Unlike standard punch grinders this solution is able to create punches with concave and convex shapes. Once the shape is designed the software will specify the wheel shape required to grind the punch. This wheel shape can then be loaded into the ANCA Wheel Editor. The Delta-C R850 drill point has been implemented in iGrind and is available in the drill wizard. This is a proprietary drill shape. Version 27 enables sharpening of this drill shape under license.
Version 27 has a wide range of applications, which enable users from many different industries to utilise its broad and flexible functionalities. Some of the more common applications which have been improved are:
Profile
Profile Pivot Editor function is a new feature of profile software. This option changes the way in which nine o'clock grinding positions the wheel. If full control is selected then the pivot angle can be specified at the start and end of each profile element. An option has been added in profile grinding that allows the feedrate to be optimised to maintain a constat passage of the grinding point across the profile.
Step
The wizard has been added to the Step editor operation that will allow a single DXF file to be split into multiple step sections. A new menu has been added to the Step Editor operation that allows geometry to be displayed and selected in iView.
About ANCA
ANCA was founded in 1974 to design and manufacture high technology Computer Numerical Controls (CNCs) for the machine tool and metal-based industries. Today, ANCA has become a leading designer and manufacturer of complete, precision CNC tool and cutter grinding machines in a global niche market.

Software improves CNC machine tool accuracy

2008-02-18T21:42:00.003-08:00

Volumetric Compensation Software corrects errors in the path of the cutting tools before they occur and thereby improve the overall accuracy of the machined product.Leading engineering companies are improving the accuracy of their key machine tools with the help of a revolutionary new software product developed in Huddersfield. One such producer is Micrometalsmiths, specialists in high precision components for the microwave electronics industry, a highly competitive field in which the need to keep abreast of the latest technology is paramount. When considering how best to meet the ever higher standards demanded by their customers Micrometalsmiths were not convinced that replacing their plant would automatically give them the edge on the competition.

At around GBP 250,000 per unit, new machine centres would come with a specified accuracy only marginally better than those currently in use.It is apparent that, even with the rapid development of recent years, surprisingly little has been done by the makers to combat the most basic threats to component accuracy inherent in every machine tool. These are geometric alignment errors and thermal distortion of the machine structure.
However, upgrade they must, so Micrometalsmiths embarked upon a collaborative project with the Centre for Precision Technologies at the University of Huddersfield, UK.

With the aim of increasing output of good components in the most cost-effective way a team of experts were given the task of enhancing the company's existing machine tools to a higher standard than ever before, even exceeding their specification when new.This ambitious plan was made possible by Volumetric Compensation Software (VCS), a ground-breaking new technology designed to correct errors in the path of the cutting tools before they occur and thereby improve the overall accuracy of the machined product.

First the performance criteria of the selected machines was measured and catalogued in minute detail. There then followed a complete mechanical and electrical refurbishment including an upgrade to the Osai series10, a controller capable of running VCS without the need for additional hardware.

There then took place a second examination by the metrology experts of the CPT, this time to determine the calibration data that was to be stored for use by VCS.Finally, the fully corrected machines were subjected to a series of exhaustive trials with remarkable results.

Volumetric error was typically reduced from 78 to 16 microns, an improved accuracy of 80%.Consequently cycle times fell by 15% and the proportion of scrap components by 30% In subsequent production trials it was found that the machines can be run faster and for longer periods of time without losing accuracy.

All-night unattended runs are now a reality and measurement cycles are executed at 3 times the speed previously possible.
Senior applications engineer Allan Kennedy said: 'I have seen the most skilled engineers spend weeks trying to achieve this level of precision and then the machine might literally change with the weather! Not so with VCS adjusting automatically in response to temperatures measured at critical points'.

'This is certainly the way forward for machine tool makers to meet the ever rising standards demanded by hi-tech industry.'

Developing an integrated STEP-compliant CNC prototype

2008-02-18T21:42:00.001-08:00

STEP-compliant CNC is the next-generation CNC controller, taking the STEP-NC data model as the interface scheme between CAM and CNC and carrying out various intelligent functions. At the moment, efforts are being made worldwide to establish an international standard for the new interface scheme (so-called STEP-NC), formal-- ized as ISO 14649. In the near future, the new interface scheme will be completed and announced as the international standard.

Upon completion, the standard will replace the conventional scheme based on ISO 6983, so-called M&G codes. Further, the new interface scheme will impact the CAD-CAM-CNC process chain and the advancement of the CNC controller. This paper develops an integrated STEP-compliant CNC system (or STEP-CNC) based on the new interface scheme. The system is composed of five modules: (1) Shop Floor Programming System (PosSFP), (2) Tool Path Generator (PosTPG), (3) Tool Path Viewer (PosTPV), (4) Man Machine Interface (PosMMI), and (5) CNC Kernel (PosCNC). The developed system is a prototype but very comprehensive, including all the modules required for realizing "art-to-part" through the new CADCAM-CNC chain. Architecture and functional details are presented together with a realistic demonstration.

As the brain for industrial machinery, computer numerical control (CNC) is the core element in modern manufacturing systems. In spite of a great deal of technological achievement, contemporary CNC still needs further enhancement to overcome the existing drawbacks; that is, (1) it is basically an executing mechanism without intelligence, (2) it is based on low-level language [ISO 6983 (ISO 1982), so-called M&G codes], and (3) its architecture is vendor specific and black-box-styled proprietary without allowing user access.

Therefore, the next-generation CNC is required: (1) to use high-level language for seamless integration in the CAD-CAM-CNC chain, (2) to be multifunctional, intelligent, and autonomous, and (3) to have an open architecture based on modular/software implementation technology. These requirements should be accounted for in developing the next-generation CNC, for which researches are being undertaken in various aspects. In particular, a new interface scheme between CAM and CNC, often called STEP-NC, is under active progress by ISO TC 184 SCI and SC4 (ISO 2000).

The new scheme is based on the internationally standardized product model (STEP: STandard for the Exchange of Product model data), formalized as ISO 10303, as well as the process plan information. As described in the next section, ISO 14649 specifies information contents and semantics (ICS) for various CNC manufacturing processes. It is currently available in FDIS (Final Draft International Standard) version, with its final version to be completed in the near future. Upon completion, it will become a new CNC language replacing ISO 6983. The impact of the new interface scheme can be visualized in many ways. As the new data model will be an information highway for e-manufacturing, encompassing CAD, CAM, and CNC, the `art-to-part' dream (Albert 2000) can be realized, thereby producing 3-D models in physical parts by CNC, like producing a hard copy from the printer. Significant gains are expected in the process chain of CAD, CAM, and CNC, as will be discussed in the next section. Furthermore, complete elimination of postprocessing is possible (Albert 2000). Soon, the new interface scheme will be used as a means for implementing the Internet's B2B activities, e-design, and e-manufacturing (Hardwick 2001a, Leyrich 2001, Albert 2001, Maniscalo 2001, Teresko 2001, Hardwick and Loffredo 2001, American Machinist 2000, Hardwick 2000).

From the perspective of CNC, the new data model is very significant, providing CNC with all the information about `what-to-make' (geometry) and `how-tomake' (process plan) with its machine tools. In other words, depending on how the new data model is implemented, CNC would be able to incorporate various intelligent functions, which is not feasible in the conventional control based on ISO 6983. Thus, as the new language is under establishment, increasing attention has been paid to the development of new CNC based on the new interface between CAM and CNC. Major developments include Super Model in the United States and NC Prototype in Europe.

The U.S. Super Model, whose prototype was presented at the 2001 SC4 meeting held in San Francisco (Hardwick 2001b), places emphasis on the development of an `intelligent interface' between the ISO 14649 database and CNC via XML and is implemented on the commercial systems of FB Mach and Virtual Gibbs. The demonstration was actually done with a Bridgeport CNC via G-code conversion. The European prototype, NC Prototype, presented at the 2000 SC4 meeting held in Charleston, South Carolina (Glantschnig 2000), focuses on CNC execution based on the part program written in the ISO 14649 physical file. The STEP-NC was implemented on a Siemens 840D NC Kernel interfaced with the commercial systems of Open Mind and CATIA. Interface between ISO 14649 and CNC was made via Interpreter built in CNC.

Software tees up savings on outsourcing

2008-02-18T21:41:00.004-08:00

An investment in Delcam's ArtCAM software and CNC routers has driven a huge increase in business at Great Lakes Golf Course Products. 'When I started here we had around 10 employees and our turnover was around $750,000 per year', said CNC Manager, Kevin Keepers. 'Now, we have 50 people and turn over that amount almost every month'.

'About 80% of our products are made using ArtCAM'.

'Without the software, the company would never have been able to grow at the pace that it has'.

Great Lakes Golf Course Products started out just over a decade ago, manufacturing recycled plastic rope stakes, hazard markers and fairway signs for local courses.

Since then, it has grown into a multi-million-dollar enterprise providing the most prestigious golf courses around the world with highly stylised, custom-tailored furnishings and amenities.

For its first six years, Great Lakes outsourced much of its custom sign work to a local sign maker and other manufacturers.

This was expensive and did not allow the company to control quality, design or scheduling.

The management realised that they could save a great deal of money and gain more control over their process by buying a CNC router and software.

After investigating a number of options, Great Lakes decided to buy an Anderson router, ArtCAM Pro and ArtCAM Insignia.

Although the company's initial needs were met by the 2D and 2.5D capabilities of Insignia, an expansion into 3D, combined with a forecast for high demand, lead Great Lakes to conclude that investment in both versions was warranted.

In the first year, the company saved US $250,000 on work that was previously outsourced.

It has subsequently bought a second router.

'Mostly, we do 2D signs and products, such as tee markers and information signs for each hole', explained Keepers.

'We also offer about 45 standard sign products which are already set up to run in ArtCAM Insignia'.

'Recently, we have been exploring the 3D side of the software more, and looking at offering more sculpted products', he added.

'We are just beginning to scratch the surface of what we can offer our customers and I am excited about this end of the business'.

'Since most of our business is custom designed, the ease of use of ArtCAM Pro and its ability to go from customer logos and artwork is a real help'.

'I really like the tracing ability, plus the ability to load the customer's artwork and fit clean vectors around it so that I can create toolpaths'.

'I also like the drawing tools in ArtCAM and find I am able to do my entire design layout in the software', he said.

'By doing the layout and design in-house, we can get instant feedback from the customer, then make any changes needed and move onto the next version'.

CADCAM software adds extra dimension to art

2008-02-18T21:41:00.001-08:00

British sculptor Alastair Mackie used the 3D laser cutting capability of Lairdside Laser Engineering Centre's Prima Laserdyne machine and Camtek's PEPS SolidCut five-axis CADCAM software to produce his latest work entitled 'Bipolar'. The work comprises a genuine US Marine's helmet into which has been cut an Islamic style fretwork pattern. The piece was exhibited at the Mark Moore Gallery in Los Angeles in Mackie's solo show entitled 'Sticks and Stones' between 13th October and 11th November, and six more pieces will be cut as a limited edition.

Not surprisingly the laser cutting of the item was not a simple engineering project.

Martin Sharp, Lairdside Laser Engineering Centre's Manager explains: 'The whole project required considerable effort from Alastair, a leading CADCAM software company and ourselves'.

'It's often the case that when an artist attempts to introduce a high-tech engineering process into his work, what often appears as a relatively simple process becomes problematic as the bounds of the technology are pushed'.

The concept was straightforward - take a 3D scan of the helmet, superimpose the fretwork pattern and then cut it.

However the steps leading to the programming of the 3D laser cutting machine are not so straightforward.

A scan of the helmet was simple to procure.

However the overlay of the pattern was by no means simple as Mackie recalls: 'It took several weeks to find someone who could do this and produce an electronic model of the sculpture'.

'Then I was able to look at my piece in 3D - but only on a computer screen'.

When Lairdside Laser Engineering Centre received the imaging file it was also able to look at its image.

But it was unable to generate the necessary CNC programming code to control the laser cutting machine.

Camtek, supplier of the PEPS CADCAM software stepped in to help.

Camtek worked on the actual computer model of the sculpture to ensure that the computer data were able to be processed by PEPS.

Terry Antrobus, Director of sales at Camtek UK comments: 'The designer used 3D Studio Max to generate the initial images of the piece'.

'DXF was the CAD format that could be provided from it'.

'The DXF data, however, yielded in excess of 20,000 3D lines, which did not have a sense of 3D orientation and were of little use for generating a five-axis laser toolpath'.

'What we were really after was a surface model of the component, but were told that this could not be provided from the imaging package'.

'Working with Lairdside, an IGES file was provided which generated nearly 7000 'wire bodies' forming a 3D facetted mesh representation of the helmet'.

'Being presented with this kind of data - thousands of unrelated 3D facets, with no sense of connectivity - can be a nightmare for or part-programmer needing to get a job out the door, or for any CADCAM salesman trying to sell his wares for that matter'.

'But generating usable data proved to be so very easy with SolidCut Laser - we were able to create usable data very quickly and automatically by generating 3D solid entities from the triangulated facets and to join them together to create a single contiguous solid model suitable for machining'.

'Applying the toolpath was equally easy'.

'Our Autocut function generated a complex five-axis laserpath including lead-in and lead-outs for all of the trims - nearly 750 individual cuts - within seconds'.

Once this was done, the PEPS SolidCut system supplied by Camtek to the Lairdside Laser Engineering Centre readily produced the optimised NC code required to drive the machine.

'The cutting of the helmet was then relatively straightforward', says Martin Sharp.

'We used the automatic 3D fixture design function integrated within PEPS SolidCut Laser to generate a nest of interlocking plates to support the helmet during cutting'.

'SolidCut Laser even nested and profiled these 2D plates for us'.

The piece was completed with only hours before Mackie flew to Los Angeles for the exhibition.

'I was overjoyed when the helmet arrived by courier the afternoon before my flight'.

'To hold in my hands what I'd only seen on a computer screen was thrilling'.

The sculpture was well received by its Los Angeles audience.

Six copies are going to be manufactured as limited editions.

'All the hard work has been done', says Sharp.

'Hopefully cutting the six helmets will be quite simple and routine'.

Quality Software & Analysis: It’s Not Just CMM Software

2008-02-18T21:39:00.001-08:00

Perhaps you have been given the job of selecting and purchasing a coordinate measuring machine (CMM) or some other geometric measurement system. Now you are comparing the various brands of equipment and trying to figure out what differentiates them, with software being a secondary consideration. If that is what you are doing, I am going to suggest that you may have the cart before the horse and would do well to reorder the decision-making process.

Consider evaluating the software first and then selecting equipment based on whether or not it is compatible with the software. Of course, the equipment must be suitable to the application. This drives everything. However, considering software first will help focus on the big picture—enterprise goals of inspection and how they can be realized more intelligently, with the highest quality results, the least effort and the lowest costs.

The idea of making measurement processes more software-centric is a core tenet of computer-aided inspection (CAI). This decade-old concept was advanced primarily within the R&D and high-tech manufacturing communities primarily because it required expensive custom measurement and analysis software to tie inspection results back to the computer-aided design (CAD) system.

Today that is changing as software developers introduce a range of off-the-shelf metrology packages with enormous amounts of built-in intelligence. These are capable of both maximizing the performance and operation of specific devices and providing a bi-directional conduit for metrology information between and amongst diverse measurement devices and CAD databases. The result is an enterprise metrology system capable of realizing the goals of inspection at speeds and efficiencies well beyond anything currently available.

Think of this new breed of measuring device software as an intelligent inspection system. As such, it is an extension of the original CAI model in that it eliminates many of the fundamental process inefficiencies associated with the traditional inspection process. Call the extended model CAIIS (pronounced case) for Computer Aided Intelligent Inspection System. This acronym provides an accurate and helpful description of the versatile inspection software tools that are becoming available from many measurement system manufacturers and third-party software providers.

CAIIS Missions

When evaluating CAIIS alternatives, it is important to keep in mind the ultimate missions of the inspection processes—transforming raw data collected by the measurement devices into actionable information to:

* Allow customers to buy off on the manufactured goods, so the enterprise can ship them, send an invoice and make a profit.
* Monitor and adjust manufacturing processes to maximize equipment uptime while eliminating scrap and rework.
* Troubleshoot design and manufacturing problems to improve product performance, reduce recalls and warranty issues and get to market faster to gain a competitive advantage.

Note that this way of thinking about inspection intelligence gets immediately into the core issues of the measurement system’s bottom-line impact. It also helps to avoid being overly distracted by technical details, which may be important to the selection process but secondary to accomplishing these objectives better, faster and with less associated cost. Off-the-shelf CAIIS packages do this because they view the goals of inspection from the enterprise solutions level, and, as such, target the bottlenecks in all aspects of the inspection process.

Primacy of CAD

Today, more and more of the work of manufacturing happens in virtual reality. Manufacturers design, model and refine products, parts and assemblies within their CAD systems. Then, using the information embedded in the CAD model, computer-aided manufacturing (CAM) systems create the tool paths for manufacturing parts with a minimal number of setups and least possible movement of parts among computer numeric control (CNC) equipment. In the virtual world, to the greatest extent possible, data is moved instead of parts, and that drives out substantial labor cost.

CAIIS is a logical extension of the CAD/CAM progression. In all but the most rudimentary measurement systems, CAD models are the basis for programming inspection routines and reporting a wide variety of actionable information. What’s more, some advanced CAIIS software can leverage design intent information that is embedded within the CAD model to generate inspection programs for the part automatically, while optimizing the program for the device that will ultimately inspect it.

Sometimes this CAIIS software resides within the CAD station. More often, it is associated with a particular measurement device or is part of a stand-alone workstation for off-line programming multiple devices. Regardless of where it lives, the CAIIS software can eliminate a substantial amount of programming labor—75% or more.

A New 80/20 Rule

" src="http://www.qualitymag.com/QUAL/Home/Images/qlt0107-FT3Soft-p3-SML.jpg" align="right" border="0"> Inspection Planner Software is CAIIS software that interprets design intent based on GD&T data embedded in the CAD model

CAIIS packages should have the intelligence necessary to automatically create measurement programs for a range of measurement devices and probe technologies and leverage the best characteristics of the device at hand to accomplish its mission.

In general, about 80% of the information required for performing inspections—programming conventions, GDT requirements and the deliverable report outputs—is common for all inspection equipment. This suggests that most of what operators need to know to inspect parts is the same whether they are using a conventional CMM, a vision system, a multisensor system, a portable measuring arm, a CMM with laser, vision or white light sensing, or a CNC machine equipped with a probe.

The 20% that is unique deals with the physical attributes of a particular device and employing best-practice conventions to leverage these attributes. The goal of a CAISS-based system is to employ the built-in intelligence of the system to create efficient programs for any of these device types with minimal operator intervention.

Here is how this 80/20 rule of CAIIS software plays out with some commonly used types of measuring devices.

* Conventional CMMs. Because of the prominence of CMMs in metrology operations, CMM software engines have evolved into the base engines for CAIIS. The best CAIIS software for CMMs works identically across a wide range of models and brands and has evolved to include the tools to realize fundamental CAIIS objectives.
* Portable arms. CAIIS software, when applied to portable arms, allows for the use of the very same programs written for CMMs. Operators can take arms anywhere in the shop or out in the field and use them to measure the parts, assemblies and tooling immediately without the need for creating new programs.
* The 20% difference in this case deals primarily with tools allowing operators to keep both hands on the arm and still interact with the computer at a short distance. Examples include the wrist mouse, magnified screens and audible signals that tell technicians when the probe is approaching the next area of interest.
* Vision systems. The CAIIS software’s programming environment for vision is largely identical to that for a CMM. Operators make measurements of all types by interacting with the CAD model, including using ultra-precision focusing algorithms to capture data from 2-D and 3-D surfaces. They can write and edit programs in any sequence and animate probe paths on-screen for fail-safe verification. Multisensor systems even incorporate traditional CMM tactile probing tools, thus using those parts of the programs requiring tactile measurements.

Here the 20% difference involves tools that allow the operator to select values related to the unique vision requirements of lighting, focus and magnification and provide help to adjust these values when a different vision system is used. The vision implementation of one CAIIS also provides unique tools that did not previously exist, such as the ability to use the vision measurement system for ad hoc measurements or to simulate measuring microscopes and optical comparators.

* On-machine probing. The programming environment for CAIIS software used to create on-machine probing routines for a wide range of CNC machines is essentially identical to the CMM version of CAIIS software. In addition, programmers can use all or parts of existing CMM programs to create on-machine probing routines directly.

In this case, the 20% difference deals with how the software vendor implements the intelligent inspection system for machine tools. The goal here is to minimize the impact on the machine’s “making chips.” Instead of driving the probe directly, programmers use the CAI intelligent software to develop and debug routines off-line. When they are happy with the results, the software translates the program into native machine code that the CNC machine can execute.

During a measurement cycle, the machine tool immediately sends the measurement data back to the CAIIS while it quickly continues on to the next cutting operation. Meanwhile, the CAIIS package performs its analytical, evaluation and reporting tasks on a separate computer. This ensures both that the measurement process has minimal impact on the manufacturing process and that it uses the best metrology tools available.
Because the goal of inspection on a CNC machine is to make fast checks to streamline setup or detect in process errors, the programs tend to be short. This allows a single CAIIS station to manage program generation, data collection and analysis for multiple machines.

Checklist

Leading metrology software manufacturers understand the importance of CAIIS principles and have embraced them. Because of the inherent importance of this technology, manufacturers can ensure that their CMMs and other measurement devices are able to make the most of this significant development. A checklist of actionable information can help during the decision-making process:

* Integration with CAD. Determine the extent to which the software can leverage CAD to automate device programming. Can it import models cleanly? Can it read embedded design intent? Can it interface directly with the CAD model?
* Software commonality. Evaluate the ability of the primary software engine to interface with and control a variety of measurement devices.
* Specific-device integration. Consider how well the software operates on and improves the performance of the specific device on which it will be used.
* CAIIS orientation. Ask the vendor to describe its plans to evolve its suite of measurement software to comply with the intent of Computer Aided Intelligent Inspection Software.

As with CAD and CAM, CAIIS operates predominantly in the virtual world to achieve critical inspection objectives with a minimal amount of labor input and with greater speed and efficiency than one would have thought possible even a year or two ago. It provides bidirectional communications to realize the big picture objectives of enterprise metrology. As long as it meets device specific applications requirements, a well-implemented computer aided intelligent inspection system is always a better choice.

CNC/PC network connectivity

2008-02-18T21:38:00.002-08:00

Turning and machining centers can now use FlexLink Ethernet connectivity from Hitachi Seiki (Itasca, IL) for its line of Seicos Sigma controls. It features software and a Universal User Port (UUP) Ethernet connection that provides bidirectional communication between the CNC machine and an external PC device or PC network.

The new design uses a standard RJ45 Ethernet connection so customers have options as to the external PC device that can be connected to the machine. Linking to a local-office PC network is the most likely application. However, it is possible to use Hitachi Seiki FlexLink technology to connect with a hand-held personal digital assistant (PDA) or a laptop computer or for use over the Internet for remote monitoring and management.

The open CNC architecture is said to be more reliable than competing designs because proven CNC controls manage the machines, while the open architecture provides real-time management information about the machine and its production. This avoids instability that might be inherent in PC-fused linkages or links dependent upon PC operating systems.

Before production, Seiki FlexLink technology provides job scheduling and production control. It can access tooling and Fixturing databases, verify CAD/CAM, or order required tools. Interactive connectivity can also provide for remote auto tuning for high-speed machining.

During production, the system provides remote diagnostics and operation. Real-time monitoring of position, programs, and displays is possible from any terminal. Event calls can be made by e-mail, and SPC data can be efficiently gathered, while remote monitoring at the management and supervisory level is available.

The system provides data for productivity analysis along with a permanent record of all machine data before, during, and after the job.

2008-02-18T21:38:00.001-08:00

The new Automatic Toolpathing (ATP) add-on, free to all Mastercam users, automates repetitive programming tasks by allowing a user to link cutting strategies to specific levels or layers containing geometry.

The program allows a user to choose machining strategies that will automatically be applied to any geometry on a specific layer or level. When selected, the program will automatically scan each layer or level and program them with the toolpath types the user chooses. It supports native MC9 files and AutoCAD DXF and DWG files.

According to the company, ATP is useful in large projects with many different pieces of geometry. Once a strategy is created, the user chooses the files to be processed. The program will then automatically batch process each individual file.

Latest CNC has easiest software yet seen

2008-02-18T21:37:00.003-08:00

Working in all materials, particularly high-grade stainless steel and aluminium, and in small volumes of often only one-off up to 100, Marcus Allum has steadily invested in CNC to satisfy customers' demanding turn-round times. Visitors to Allum Precision Engineering's rural site in Berkshire are easily lulled into a false impression of the company as they travel down a dirt track, with open fields on either side and towards a series of traditional farm buildings. From the outside, there is no indication that the ageing stable block is home to a high-tech machining centre and other CNC machines that are proving key in the supply of precision components to a wide range of local manufacturers.
Even since Marcus Allum formed the company in the mid-'90s, when the initial manual machines - a lathe and a turret mill - were being operated from a trailer while awaiting planning permission to use the outbuildings for light industrial use, he has continually strived to at least remain on par with his competitors, but preferably one step ahead.

This he has succeeded in doing through combining clever and innovative engineering with regular investment in CNC machining - the latest of which is a Gate Challenger VMC-610 vertical machining centre, fitted with Anilam CNC, from Gate Machinery International.

His current order book includes a wide range of precision-engineered parts for the automotive sector (ie, exhaust fittings), telecommunications (mobile 'phone components), aircraft (microlite wing struts) and oilfield and chemical industries (vacuum compressor heads) as well as a plethora of 'hobby' jobs such as the refurbishment and replacement of locks and keys for churches.
Working in all materials, particularly high-grade stainless steel and aluminium, and invariably in small volumes of often only one-off (prototype work) and batches of no more than 100, Marcus Allum has steadily invested in CNC to not only utilise the machines' higher speeds and feeds, to satisfy customers' demanding turn-round times and the required consistent quality of often complex components, but also to overcome a problem that is familiar to many companies - lack of skills.

'Although I have the services of two or three skilled operators on a part-time basis, the use of CNC milling and turning has largely enabled me to solve this perennial problem,' he says.

CNC needs CNC support - computer numerical control machines

2008-02-18T21:37:00.001-08:00

Outdated secondary-operation machines were strangling the productivity of a Chicago-area screw machine shop's impressive battery of CNC screw machines. Now, CNC drilling and tapping machines and turning centers are providing secondary machining efficiency that has raised the firm's performance to a level few competitors can match.

When you drive past the building, with its concave front and narrow, close-set, floor-to-ceiling windows, you would guess an insurance firm, or an engineering or architectural firm, or perhaps an association office. In fact, the distinctive exterior pictured in Figure 1 houses the operations of General Automation, Inc., one of the most impressive screw machine shops in the country.

General Automation specializes in, among other things, Swiss screw machine parts, that is, workpieces with high length-to-diameter ratios. The firm produces them on numerous Swiss-type cam automatic screw machines, arranged like spokes on large wheels, bar feeds toward the center. (The arrangement makes the most efficient use of floor space and makes it easier for the operators to load the machines and tend their operation.)

Although cam-operated screw machines have been around for generations, they remain a very competitive method for producing workpieces in large quantities. They can produce workpieces in less time (a shorter cycle) than by most other methods.

But cam automatics are inefficient when the job involves making a few prototypes, or a small quantity of workpieces, or when machined part dimensions must be accurate to one or two ten-thousandths of an inch. Such jobs are best handled on CNC screw machines.

Advantages Of CNC

Screw machine shops are aware of the advantages of CNC screw machines; many have one or two in order to remain competitive on prototype work, short run jobs, and jobs where fast turnaround and/or high quality are critical. However, few shops are in a position to invest in enough CNC screw machines to comprise a separate department.

General Automation is one of the few. The firm operates some 63 Nomura CNC Swiss-type screw machines--the largest concentration of such machines in the U.S. The CNC Swiss-type screw machine offers a number of advantages over the older cam automatic screw machine. As its name implies, the cam automatic's cutting tool movements are controlled by a set of cams specially made for the workpiece being produced.

The CNC screw machine needs no cams. Tool movements are automatically determined by data from the dimensions of the part, fed into the machine's CNC unit. The workpiece can be programmed on the CNC right at the machine. Or, as is more often the case, the program can be prepared on a programming system located off the shop floor, and loaded in the machine's control when required. The control's "memory" is capable of storing dozens of workpiece programs; preparing the CNC screw machine to produce a different workpiece simply involves calling up the program for the next job, minimizing machine downtime between jobs.

Because CNC machine tools handle job change-overs much faster than manual or automatic machines, they are usually thought of as "short-run machines." By contrast, cam automatics, which are noted for their very rapid cycle times, are considered "production machines," ideal for producing large quantities of workpieces over long periods of time.

Enhanced CNC software is rougher than before

2008-02-18T21:35:00.002-08:00

Enhancements for rough machining, as well as new flat land finishing cycles and toolpath simulation are key developments by Pathtrace of Reading to its top-selling EdgeCAM offline CNC programming software. The result is that the productivity of EdgeCAM users can be further enhanced by the improved generation of machining cycles and overall production competitiveness.

The improvements included in the recently-announced EdgeCAM Version 6.75 are part of the commitment by Pathtrace to the software's continuous development by incorporating industry-leading cutting techniques and machine tool capabilities as well as ensuring seamless integration with all the major CAD systems.

Over the last six months, this development strategy has been reflected by record sales of EdgeCAM within the production and mould and die sectors in both the UK and increasingly overseas as customers look for ways to improve productivity without major capital expenditure.

One important improvement to the machining of thin-walled pockets incorporated in the latest EdgeCAM roughing cycle's finer cut strategy is the ability to reduce tooth loading of the tool during the final cutting pass.

In addition, a new checkbox, which provides an option for the software to treat open pocket type features as if they were closed pockets, allows different stepover values to be applied to the final pass as each separate z-level is machined.

Machining time can also be significantly reduced by EdgeCAM's ability to initially create the main cuts first, followed by intermediate cycles taken from the bottom to the top of each individual region.
Also, a new option entitled 'boundary' is added to the listing of roughing cycle stock types, and this accommodates the selection of both a stock and a containment boundary.

Shop improves manufacturing with simulation software

2008-02-18T21:35:00.001-08:00

Tell Tool of Westfield, Mass., has integrated Vericut CNC simulation software into its NC-program prove-out process. It ensures every part is accurate, dimensionally correct, and efficient when they hit the shop floor. As a result, the company reduces manual prove-out processes by as much as 80% and practices lights-out machining on some of its first-time parts to improve efficiency, productivity, and profitability.

Besides electronic engine controls, auxiliary power units, and other systems, Tell Tool manufactures fuel-control units using Vericut's model export capability integrated into the manufacturing process. When customers contract Tell Tool for a fuel-control unit, there is often no design model of the final part shape. What Tell Tool gets are specifications for the dimensions of the inside of the part, minimum wall thicknesses, specific structure requirements, and other information.

To create the outer shape of the control unit, Tell Tool reverse engineers the unit from the inside out using internal-part specifications such as fuel-control-housing dimensions and the minimum wrap-stock requirements around each feature. Within a CAD/CAM system, it creates cutter paths around the minimum wrap-stock requirements, which run in Vericut to create the in-process part shape.

Vericut exports the in-process shape as an in-process file that converts to an STL file, which serves as a starting point for programming the next operation in the CAD/CAM system. After the part is programmed and run through Vericut, there is an in-process model of the fuel-control housing's shape. This finished shape, which can convert to an STL file, goes back to the customer.

Prior to implementing Vericut, programmers approximated as to the shape of the in-process material and ran the cutter path within those imaginary boundaries. As a result, there were a lot of air cuts where the cutter did not contact material.

For companies like Tell Tool, the latest release of Vericut, version 5.4, also improves documentation processes. Such software contains the critical manufacturing information, especially a representation of the in-process geometry, necessary to accurately document a process. One example is creating inspection instructions. Vericut 5.4 automatically creates inspection instructions complete with in-process feature dimensions, which are generated during NC-program simulation. Most shops manually create inspection instructions. However, without an electronic in-process model of the part, there is a limited knowledge of the in-process state of material. Thus, manual methods require a certain degree of technical expertise and are prone to error.

Working with cnc software

2008-02-07T21:09:00.003-08:00

Good cnc software is essential for your machine. As the software tells your machines what to do and where to do it, so that your unit can execute the pattern you have input perfectly every time. There are many different vendors of cnc software. Most cnc machines come preloaded with software designed specifically for that machine. However, some users may find that the one that comes with their machines is too limiting, or that it conflicts with their CAD programe or operating system.

Fortunately aftermarket cnc programs are available, and these products allow users to customize their machine tools to suit their specifications.

Special software allows users to input their own programs in one platform, rather than having to use several programs to produce a single pattern. With cnc programming software, users can write their code in one place, and will most often be able to produce patterns without having to write programs in another format.cnc software center The advantage of this flexibilitylies in time savings, as well as avoiding the possibility of data loss or incompatibility issues as you transfer data from one program to another.

One of the most exciting aftermarket products for CNC routers is 3D software. With 3D cnc software, the user would be allowed to produce precisely carved 3D patterns, which can be especially useful for signs or other wall hangings. One great feature of 3D cnc software is the ability to import images from other sources. Most software accepts .gif and .jpg images, and it is amazing how well these images are reproduced in startling 3D. With a tool like 3D cnc software in your workshop you can produce beautiful and intricate carvings and engravings, which can then be painted with realistic colours to make them come alive.

If your machine came with a good suite of software you may be unwilling to pay for aftermarket software. There are many free cnc software programs on the Internet, and these can help you try new programs without having to make a major purchase. Some of these free cnc software programs are demonstration versions, while others are fully featured programs with little or no limitations.

Quality Software & Analysis: It’s Not Just CMM Software

2008-02-07T21:04:00.001-08:00

given the job of selecting and purchasing a coordinate measuring machine (CMM) or some other geometric measurement system. Now you are comparing the various brands of equipment and trying to figure out what differentiates them, with software being a secondary consideration. If that is what you are doing, I am going to suggest that you may have the cart before the horse and would do well to reorder the decision-making process.

Consider evaluating the software first and then selecting equipment based on whether or not it is compatible with the software. Of course, the equipment must be suitable to the application. This drives everything. However, considering software first will help focus on the big picture—enterprise goals of inspection and how they can be realized more intelligently, with the highest quality results, the least effort and the lowest costs.

The idea of making measurement processes more software-centric is a core tenet of computer-aided inspection (CAI). This decade-old concept was advanced primarily within the R&D and high-tech manufacturing communities primarily because it required expensive custom measurement and analysis software to tie inspection results back to the computer-aided design (CAD) system.

Today that is changing as software developers introduce a range of off-the-shelf metrology packages with enormous amounts of built-in intelligence. These are capable of both maximizing the performance and operation of specific devices and providing a bi-directional conduit for metrology information between and amongst diverse measurement devices and CAD databases. The result is an enterprise metrology system capable of realizing the goals of inspection at speeds and efficiencies well beyond anything currently available.

Think of this new breed of measuring device software as an intelligent inspection system. As such, it is an extension of the original CAI model in that it eliminates many of the fundamental process inefficiencies associated with the traditional inspection process. Call the extended model CAIIS (pronounced case) for Computer Aided Intelligent Inspection System. This acronym provides an accurate and helpful description of the versatile inspection software tools that are becoming available from many measurement system manufacturers and third-party software providers.

CAIIS Missions
A range of portable measurement systems, such as the laser tracker and measuring arm, can be programmed and operated using common CAIIS software based on the PC-DMIS CMM engine. Source: Wilcox Associates

When evaluating CAIIS alternatives, it is important to keep in mind the ultimate missions of the inspection processes—transforming raw data collected by the measurement devices into actionable information to:

* Allow customers to buy off on the manufactured goods, so the enterprise can ship them, send an invoice and make a profit.
* Monitor and adjust manufacturing processes to maximize equipment uptime while eliminating scrap and rework.
* Troubleshoot design and manufacturing problems to improve product performance, reduce recalls and warranty issues and get to market faster to gain a competitive advantage.

Note that this way of thinking about inspection intelligence gets immediately into the core issues of the measurement system’s bottom-line impact. It also helps to avoid being overly distracted by technical details, which may be important to the selection process but secondary to accomplishing these objectives better, faster and with less associated cost. Off-the-shelf CAIIS packages do this because they view the goals of inspection from the enterprise solutions level, and, as such, target the bottlenecks in all aspects of the inspection process.

Primacy of CAD

Today, more and more of the work of manufacturing happens in virtual reality. Manufacturers design, model and refine products, parts and assemblies within their CAD systems. Then, using the information embedded in the CAD model, computer-aided manufacturing (CAM) systems create the tool paths for manufacturing parts with a minimal number of setups and least possible movement of parts among computer numeric control (CNC) equipment. In the virtual world, to the greatest extent possible, data is moved instead of parts, and that drives out substantial labor cost.

CAIIS is a logical extension of the CAD/CAM progression. In all but the most rudimentary measurement systems, CAD models are the basis for programming inspection routines and reporting a wide variety of actionable information. What’s more, some advanced CAIIS software can leverage design intent information that is embedded within the CAD model to generate inspection programs for the part automatically, while optimizing the program for the device that will ultimately inspect it.

Sometimes this CAIIS software resides within the CAD station. More often, it is associated with a particular measurement device or is part of a stand-alone workstation for off-line programming multiple devices. Regardless of where it lives, the CAIIS software can eliminate a substantial amount of programming labor—75% or more.

A New 80/20 Rule

" src="http://www.qualitymag.com/QUAL/Home/Images/qlt0107-FT3Soft-p3-SML.jpg" align="right" border="0"> Inspection Planner Software is CAIIS software that interprets design intent based on GD&T data embedded in the CAD model

CAIIS packages should have the intelligence necessary to automatically create measurement programs for a range of measurement devices and probe technologies and leverage the best characteristics of the device at hand to accomplish its mission.

In general, about 80% of the information required for performing inspections—programming conventions, GDT requirements and the deliverable report outputs—is common for all inspection equipment. This suggests that most of what operators need to know to inspect parts is the same whether they are using a conventional CMM, a vision system, a multisensor system, a portable measuring arm, a CMM with laser, vision or white light sensing, or a CNC machine equipped with a probe.

The 20% that is unique deals with the physical attributes of a particular device and employing best-practice conventions to leverage these attributes. The goal of a CAISS-based system is to employ the built-in intelligence of the system to create efficient programs for any of these device types with minimal operator intervention.

Here is how this 80/20 rule of CAIIS software plays out with some commonly used types of measuring devices.

* Conventional CMMs. Because of the prominence of CMMs in metrology operations, CMM software engines have evolved into the base engines for CAIIS. The best CAIIS software for CMMs works identically across a wide range of models and brands and has evolved to include the tools to realize fundamental CAIIS objectives.
* Portable arms. CAIIS software, when applied to portable arms, allows for the use of the very same programs written for CMMs. Operators can take arms anywhere in the shop or out in the field and use them to measure the parts, assemblies and tooling immediately without the need for creating new programs.
* The 20% difference in this case deals primarily with tools allowing operators to keep both hands on the arm and still interact with the computer at a short distance. Examples include the wrist mouse, magnified screens and audible signals that tell technicians when the probe is approaching the next area of interest.
* Vision systems. The CAIIS software’s programming environment for vision is largely identical to that for a CMM. Operators make measurements of all types by interacting with the CAD model, including using ultra-precision focusing algorithms to capture data from 2-D and 3-D surfaces. They can write and edit programs in any sequence and animate probe paths on-screen for fail-safe verification. Multisensor systems even incorporate traditional CMM tactile probing tools, thus using those parts of the programs requiring tactile measurements.

Here the 20% difference involves tools that allow the operator to select values related to the unique vision requirements of lighting, focus and magnification and provide help to adjust these values when a different vision system is used. The vision implementation of one CAIIS also provides unique tools that did not previously exist, such as the ability to use the vision measurement system for ad hoc measurements or to simulate measuring microscopes and optical comparators.

* On-machine probing. The programming environment for CAIIS software used to create on-machine probing routines for a wide range of CNC machines is essentially identical to the CMM version of CAIIS software. In addition, programmers can use all or parts of existing CMM programs to create on-machine probing routines directly.

In this case, the 20% difference deals with how the software vendor implements the intelligent inspection system for machine tools. The goal here is to minimize the impact on the machine’s “making chips.” Instead of driving the probe directly, programmers use the CAI intelligent software to develop and debug routines off-line. When they are happy with the results, the software translates the program into native machine code that the CNC machine can execute.

During a measurement cycle, the machine tool immediately sends the measurement data back to the CAIIS while it quickly continues on to the next cutting operation. Meanwhile, the CAIIS package performs its analytical, evaluation and reporting tasks on a separate computer. This ensures both that the measurement process has minimal impact on the manufacturing process and that it uses the best metrology tools available.
Because the goal of inspection on a CNC machine is to make fast checks to streamline setup or detect in process errors, the programs tend to be short. This allows a single CAIIS station to manage program generation, data collection and analysis for multiple machines.

One important improvement to the machining of thin-walled pockets incorporated in the latest EdgeCAM roughing cycle's finer cut strategy is the ability to reduce tooth loading of the tool during the final cutting pass.

In addition, a new checkbox, which provides an option for the software to treat open pocket type features as if they were closed pockets, allows different stepover values to be applied to the final pass as each separate z-level is machined.

Machining time can also be significantly reduced by EdgeCAM's ability to initially create the main cuts first, followed by intermediate cycles taken from the bottom to the top of each individual region.
Also, a new option entitled 'boundary' is added to the listing of roughing cycle stock types, and this accommodates the selection of both a stock and a containment boundary.
