The Microgage is a 3D desktop CMM designed for reliability and thermal stability. Available from Helmel, the CMM delivers volumetric accuracy of better than 5 micrometers. It has repeatability of 0.7 micrometer and scale resolution of 0.1 micrometer. The fixed-bridge design incorporates a moving stage for the Y axis. XYZ travels are 225 mm × 150 mm × 125 mm, with precision linear bearings in the X and Y axes and instrument roller bearings in the Z axis. Accuracy is intrinsic; error mapping and volumetric error compensation are not used. The machine is capable of dimensional inspection, scanning and reverse engineering of parts. It uses the company’s Geomet CMM Metrology Software and motion control, which provides operators with control over geometric measurement, analysis and programming.
