In the first part of this two-part series, I looked at what actually happens in the cutting zone and how that knowledge allows end users to select the best possible cutting tool and CAD/CAM strategy for a particular material to optimize material removal. This second part covers why it is important to adopt this approach not only for all CNC machining processes, but as a significant production cost-saving measure companywide and industrywide.

NIST: Fortify Manufacturing, Save $100 Billion, by Closing Tech Gaps

To spur significant innovation and growth in advanced manufacturing, as well as save over $100 billion annually, U.S. industry must rectify currently unmet needs for measurement science and "proof-of-concept" demonstrations of emerging technologies. This is the overall conclusion reached by economic studies funded by the National Institute of Standards and Technology (NIST) of four advanced manufacturing areas used to create everything from automobile composites to zero-noise headsets.

With an assist from sound that humans can’t hear, machining can be a cooler and faster process—and yield more accurate results to boot, according to the September 2016 Machine Technology column in Cutting Tool Engineering magazine.

Iscar video depicts chip forming

The cutting edges of cutting tools don’t actually produce chips. Instead, the pressure of a rapidly spinning tool on a workpiece plasticizes part of the parent material, creating a shearing effect that forces the material to ride up the tool. The flute and tool geometries form the chip and force it away from the tool body until it breaks off and evacuates.

Iscar Metals Inc. produced this video depicting this process. 

Nikkei: DMG Mori head bearish on global capital investment

"Global capital investment, a main engine of economic growth, remains stagnant amid concerns over a slowdown in emerging markets and the U.K.'s vote to leave the European Union, writes Mikio Sugeno in Nikkei Asian Review. "Masahiko Mori, president of major Japanese machine-tool manufacturer DMG Mori, painted a downbeat picture of global business investment in an interview with The Nikkei, saying that a full-scale recovery is still two to three years away." Mori explains his reasoning in this Q&A with Sugeno.

Machining Center May Hold Key To Connecticut's Aerospace Future

“The 30-foot-by-35-foot pit in a concrete floor is empty, shiny and immaculate as it awaits the arrival of a massive machine for use by Connecticut manufacturers to cut, shape and do a range of other tasks with composite materials,” writes Stephen Singer in the Hartford Courant. “At the Connecticut Center for Advanced Technology in East Hartford, the large rectangular hole resembling a swimming pool and reaching a depth of 4 ft. in parts will be filled later this year by the 130,000-lb, high-speed industrial machine [that] will be used to shape, cut, grind and otherwise fashion aerospace and other industry components made of composites.”
