A compact, precise coordinate measuring machine (CMM) developed for measuring small parts (300 x 200 x 200 mm) with comparatively high speed has become available from Mitutoyo America Corp. (Aurora, IL; www.mitutoyo.com). Called the Legex 322, the machine offers an accuracy of MPEE= [0.8+2L/1,000]µ and a speed of 200 mm/sec, with an acceleration of 520 mm/sec2. The machine has a one-piece configuration that was based on FEM analysis, taking into account the potential geometric deformations that can occur during typical measuring operations. The Y-axis rail is ceramic coated; there is real-time temperature compensation to assure accuracy. The Legex 322 can be fitted with contacting, scanning, touch-trigger, laser, and vision probes. The software platform—MCOSMOS—is said to provide support for virtually every CAD format.
