Today, the productivity needed to be globally competitive requires ever increasing metal-removal rates during operations such as roughing and high-speed slotting. Process reliability is paramount, especially when working with difficult-to-machine materials.
Overall, there are two overriding customer needs: reducing cycle time and machine downtime. They want higher feed rates and depth of cut for greater metal removal.
Today’s products require high finishes, burr-free edges, freedom from contamination, and often close tolerances. Electropolishing provides all of those conditions and more in a matter of seconds for many metal parts. It is a process that has been used for more than a hundred years. It is widely known and the science is widely discussed, but its ability to run job shop lots and high-precision high-volume parts in the same equipment makes it a bit unique.
It is reported that, not too long ago, before the current precipitous decline in machine-tool shipments, the number of 30-taper machines that were being manufactured and sold in Japan had surpassed the numbers of 40-taper and 50-taper machining centers.
Methods Machine Tools Inc. (Sudbury, MA), a leading supplier of precision machine tools, 3D printing technology and automation, recently introduced an automation cell designed to greatly boost 3D manufacturing throughput.
Kennametal Inc. (Pittsburgh) announced June 29 that its board of directors has appointed Christopher (Chris) Rossi as president and CEO and has named him a director. Rossi succeeds Ron De Feo, whom the board has appointed executive chairman. Both appointments are effective August 1.
Mitutoyo America Corp. (MAC; Aurora, IL) celebrated the grand opening of its new Detroit-area M3 Solution Center in Novi, MI, on June 28. The 8455 ft2 (785.5 m2) facility replaces one that the company had occupied for 38 years in nearby Plymouth, MI.
The challenges to manufacturing as it evolves into the 21st century are now familiar, and impact how metrology must contribute. Manufacturers face uncertain production volumes with roller-coaster demand, shorter production runs and faster product development cycles. Automation, while alluring as a way to reduce cost, needs to adjust.
Why use a metrology device on or near a machine tool? It isn’t just useful for making sure a tool is present or monitoring tools for wear or breakage. On-machine measurement technologies can save time and money, by speeding up processes and eliminating extra personnel, and they are a critical step in the movement towards “lights-out” manufacturing.
Micro components continue to shrink in size, demanding ever-greater precision and improved handling of parts with sub-micron-sized features. New approaches in micro machining technology include higher-precision systems from traditional micro machining developers, as well as techniques using additive manufacturing processes and semiconductor wafer-scale technology on the smallest of micro parts.
