Lori has been working “behind the scenes” of Production Machining since 2003, writing and editing the Products, News and Case in Point sections of the magazine, editing other staff members’ articles, and more recently, writing a column for PM’s e-newsletter, Inbox Insights. She began her journalism career in the trucking industry, writing technical articles for two trade publications. She has a B.A. in Communications from the University of Dayton.
Last month, more than 400 students were certified in Mastercam CAD/CAM software in the Broward and Dade Counties in Florida. In that state, Mastercam is on the recognized list for funding, therefore, schools can be reimbursed for each student who earns an industrial certification.
"This is a big deal because of the amount of students that are becoming certified," says Dustin Spieth in the Mastercam's corporate educational office, who travels to Florida each year to administer the certification program.
While in Florida, Dustin conducts a class to teach new instructors the certification program and also shows experienced instructors any new changes to the certification program.
Mastercam certification is a rigorous set of knowledge-based and practical tests that demonstrates a programmer's ability to work effectively with CAM software, overcome common issues facing today’s shops, and produce high quality finished parts. There are two certification levels: Associate Level and Professional Level. Associate Level is comprehensive testing based on the latest technologies, while Professional Level includes the comprehensive testing combined with a practical application component.
Okuma's VSST allows users to cut threads without chatter.
Eliminating harmonics, which can produce tool chatter or poor surface finish, is critical for maximizing CNC lathe productivity. Harmonic Spindle Speed Control (HSSC) and Variable Spindle Speed Threading (VSST) are functions built into Okuma’s Thinc-OSP CNC control that are harmonics problem solvers. HSSC and VSST are particularly useful when machining parts with high L/D ratios, thin-walled parts or thin-walled parts with threads.
Avoiding scrap caused by harmonic-induced vibration can be a challenge using conventional solutions. HSSC and VSST functions on an Okuma CNC lathe make it easier to achieve consistent surface finishes on parts, the company says.
Okuma’s HSSC and VSST is described in the company’s white paper.
Keeping inspection close to machining prevents quality from becoming a bottleneck.
There are strategies involved in achieving lean for a shop, but like going on a diet, lean doesn’t happen overnight and it takes some work on your part to get your shop in shape. In "Tips to Lean on for Becoming Lean," I’ve compiled some tips on how to turn a shop lean, and I’ve included links to several articles PM has written, so you can read more about it.
The steps may involve reorganizing your equipment into machining cells, understanding customer needs, cross-training employees, upgrading technology—all ideas based on creating a successful manufacturing business for a long time to come. Read more here.

The multiple streams of pressurized coolant at the cutting edges. This method of coolant delivery also flushes chips out of the cutting zone.
Controlling heat at the tool/workpiece interface is an operator’s main concern. Therefore, the idea of a tool that effectively controls heat with a special grade of carbide, a new coating and internal channels that deliver cooling through ports in the shank where the milling flutes begin, is worth a look.
According to the article, these cutters are capable of significantly higher cutting speeds and depths of cut in tough-to-machine materials compared with conventional end mill designs in this size range. These results are obtainable in stainless steel, titanium, chrome-cobalt alloys and other so-called super alloys. Read more here.
