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.

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.

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.

Tool presetting machines are a wise investment for machine shops that want to increase their machine utilization. Idle machine tools are often indicators of inefficient machining operations, and stopping a machine tool for any reason is synonymous to losing profits.

You don’t have to look too far to find tooling presetters that fit the machining requirements of just about any size shop. The value of off-line tool presetting—rather than stopping machine spindles to touch off tools as machines sit idle—continues to prove itself invaluable, especially to the smallest first-time user shops.

Mitsui Seiki USA, Inc. announced that Scott Walker, long-time president, has accepted the position of chairman; Robb Hudson, former business and technology director, has been named chief executive officer; and William “Bill” Malanche, former executive vice president, has been appointed chief operating officer.

The timeframe and sheer size of the workpieces required Weingärtner to scale up one of its advanced technology mpmc 1200 machining centers to be able to machine giant turbine shafts used in gas/steam turbine plants.

Challenged by an increasingly niche-oriented automotive market, The Chrysler Group (Auburn Hills, MI) must increase the number of models it offers while decreasing its capital investment. The company plans to offer 50% more models in 2009 compared to 2004, according to John Felice, VP of manufacturing, technology and global enterprise for Chrysler.

Automation in manufacturing is more important than ever, reducing costs and improving quality. While it is important in assembling cars, machining engines, or drilling holes in airframes, is it important to metrology operations as well? “Absolutely,” explained Michael Kleemann, engineering manager VRSI (Plymouth, MI).
