Geometric CAMWorks speeds up milling for Magnus Hi-Tech

Geometric' CAMWorks speeds up milling for Magnus Hi-Tech

Mumbai, India, February 10, 2010: Florida-based Magnus Hi-Tech Industries Inc. (www.magnusht.com), an established world-class precision fabricator, has experienced reduced engineering and CNC programming time by using CAMWorks®, an intuitive solids-based CAM solution from Geometric Limited.

Magnus Hi-Tech provides high quality solutions to its customers for all their fabrication needs in the defense, aerospace, medical and other demanding fields. Using advanced sheet metal fabrication and machining technology, coupled with rigorous quality methodologies, Magnus provides an impressive range of products including holding brackets, complex components for military simulators, housings, struts, mounting blocks, impellers, and military chassis.

Magnus recently started using the Mazak 5-axis CNC milling machine to reduce changeover times and machine downtime, and realized that the CAM software being used was not letting it take the full advantage of the milling machine, and needed an application that was easily compatible with the SolidWorks® platform that the company used.

Magnus selected Geometric's CAMWorks, which provides an array of tools to simplify and automate even complex programming tasks, speeding design and programming changes.

Mike Blake, Methods Engineer/ Program Manager for Magnus Hi-Tech says, "CAMWorks' tight integration with Magnus Hi-Tech's SolidWorks environment facilitates true associative machining, so that any revision to a part design updates the SolidWorks solid model as well as the CAMWorks file, permitting CAMWorks to automatically generate the new toolpaths, the tool list and, if required, the fixture modifications as well. This has resulted in time savings on revisions ranging from 20 to 60 percent."

CAMWorks, the first SolidWorks® certified Gold CAM product, and the first CAM solution to offer knowledge-based feature recognition and associative machining capabilities, helps eliminate the drudgery of CNC programming. The combination of the latest innovations in CAMWorks and SolidWorks' excellence in design, have made CAMWorks the premier CAM solution for manufactures in the automotive, aerospace, electronics and medical industries.

"CAMWorks is always making improvements to their product and staying abreast of technology," concludes Blake, "that is the same philosophy we have at Magnus Hi-Tech."

The stock was trading at Rs.63.80, up by Rs.3.35 or 5.54%. The stock hit an intraday high of Rs.66.45 and low of Rs.60.50.

The total traded quantity was 1281243 compared to 2 week average of 197529.

The reasons for poorly skilled CNC machinists

The reasons for poorly skilled CNC machinists

Posted by Bert Maes on February 9, 2010

Forums offer great blog material. They show you many different takes and perspectives on one subject. Here is one:

In August 2008 williamshook2003 posted a message on the American Machinist Forum, title “Poorly trained machinist”.

He said that students fresh from school didn’t learn the basics there. They don’t know how to read a rule or a tape measure, how to hand-sharpen a drill, they don’t know anything about speeds and feeds, anything about basic trigonometry.

flatbeltbob wrote down the story a real-life situation in his shop:

The local high school sent me a junior to observe what goes on in a small machine shop – Just to see if that is something he might want to pursue. I tried to show him how a PI tape works:

-          Never heard of PI, no idea what I’m talking about.

-          OK , back up and lets read a tape measure.

-          How many inches in a foot ?

-          Not sure , but knows 2 feet is longer that one foot.

-          OK , lets look at one inch. If you take one inch and divide it into 8 equal parts, then how many eighths are in one inch?

-          “six?” he says.

Does this represent the future pool of machinist talent ?

Why is that the forum visitors ask themselves:

  • Because they rely too have on their computer skills and CAM software and assume that that program is making the machine cut in the best conditions, williamshook2003 answered.
  • Chuck added: young people see manual equipment as archaic and they state that shops need to get into CNC to be really productive. That is true, but without the training on manual equipment first, new machinists don’t understand what is going to happen when they push the start button on a CNC machine.
  • There are few good instructors,” Byron L. commented, “we haven’t even been taught in any basics, except the first week: using a file.”
  • Industrial Arts, metal shop and other trade related training is taken out of the High Schools. Consequently, we hurt our ability to attract, training and inspire new blood for this and other craft skills, said Eagle_view.
  • Chuck commented as well: the trend of poorly skilled machinists is not surprising as CNC machines are automating the production process, so where and why do we still need highly trained machinists?
  • Shop owner reacted on this statement, saying that we cannot blame the technology. We should blame the employers for not training their employees on the basics. Bluechipfan agrees: “There are actually some really smart talented kids but they need direction and guidance. That, folks, is where WE come in. You will be surprised but it requires great patience and perseverance.
  • Eagle_view takes a bit a broader look (as his name betrays) and says that because kids are being raised without a father figure in the home, they have no idea how to fix things, how to work with their hands and they don’t know anymore how things are made. “When we as a society decided that we were not going to produce anything except for information we kind of burt some bridges that we may need”.
  • According to PackratFXR we have to go back to the basics. The machine tool technology is changing daily, but the operator should know more than changing tools, watching coolant, and feeding raw stock. To fix problems, we need hands-on training!
  • littlebrewman could’t agree more: “I will always have a marketable skill and know that I can survive, cause I can do more than press the green button.”

How can I use subprograms to increase productivity on my machining center?

How can I use subprograms to increase productivity on my machining center?

Generally speaking, subprograms do not increase throughput for a machining operation. The real benefit of using subprograms is to decrease setup time and NC file size.
Subprograms allow you to repeat a portion of a program many times. For instance, if you had a particular section of a program that needed to be repeated several times, instead of copying that section of the program over and over (and ending up with a very large NC file), you could use a subprogram. You would write the subprogram section once, then refer to it as many times as you need to.

For example, suppose a very sophisticated design needs to be cut into a piece of steel with a 0.050” end mill. The total depth of the cut needs to be 0.125”; a much deeper cut than the small end mill can make.
Through experience we know that the deepest we can cut at any one time is 0.005”. Therefore we can calculate that we need to make 25 passes on the X,Y plane to reach the final depth of 0.125”. Let’s assume that the code required to make just one of these passes is 2000 blocks. If we used a CAM package to generate a program with the 25 passes, we would end up with an NC program with 50,000+ blocks.

The alternative is to use the CAM package to generate a program that provides one pass in the XY plane. We could then manually add the subprogram codes necessary to “call” that section 25 times (incrementally moving the Z axis down 0.005” each time). Not only would this save considerable disk space, but we would end up with a program that machines the same part in only 2010 blocks, a considerable savings.
For information on building and utilizing subprograms, refer to your User’s Guide.
