Flexible Fixturing Speeds CMM Inspection By Derek korn M any shops use quick-change workholding devices on their CNC machine tools to speed and simplify change-overs. Kay-Jay Products, a subsidiary of Phillips Precision, says its Inspection Arsenal product line enables users to apply the same time-saving concept to CMM inspection routines. Inspection Arsenal is a collection of modular fixturing components that offers an alternative to using traditional glue, clay and tape as well as more costly precision clamps and dedicated fixtures. According to the company, it can help open CMM bottlenecks and reduce machine tool downtime by speeding first-article and/or inprocess part measurements. A video at short.mmsonline.com/ia demonstrates how to set up the fixturing system atop a CMM's table. Inspection Arsenal is a quick-change CMM fixturing system designed to speed measurements of various workpieces. 28 MMS September 2013 mmsonline.com Inspection Arsenal components include the Loc-N-Load fixture plate system that easily installs atop a CMM's table. The two primary components of this system are docking plates and fixture plates onto which various clamping devices can be installed. The 0.5-inch aluminum plates interlock like pieces of a puzzle and use embedded steel and magnetic inserts to remain tightly secured to one another. During installation, a docking plate (18- or 30-inch-long versions are available) fastens to one end of the CMM's table to accept the fixture plates. The docking plate mounts outside of the CMM probe's travel to maximize the inspection envelope. A plate designed to accept a qualifying
