VMCs have had a productive past, present and the future looks promising

“Metrology and its relationship to manufacturing is rapidly evolving,” Ken Woodbine, president, Wilcox Associates, a brand of Hexagon Metrology (North Kingstown, RI), recently observed. “We are seeing larger quantities and faster speeds of measurement data collection. The next challenge is what to do with all that data.”

Until the middle of 2010, first-tier subcontract machinist, JJ Churchill, could produce turbine blades only if they had their fir-tree root-forms preground elsewhere, or if they were subsequently added by another subcontractor. No longer is this the case.

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.

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.

It’s a sad fact of practically all metal removal operations that, no matter how sharp the tool or free-machining the material, there are going to be burrs, hanging chads, ragged corners, and other edge quality issues that must be dealt with before calling the workpiece complete.

Milltronics USA has named Foothills Machinery Sales as its exclusive full-service distributor for the states of Colorado and New Mexico.

Horn Technology Days, hosted by Paul Horn GmbH every two years, is a celebration of manufacturing and what is possible with modern cutting tool technology. This year’s event coincided with the company's 50 year anniversary and featured three days of technical sessions, factory tours and practical demonstrations of the company’s manufacturing products.
