Machine checking gauge (MCG) for monitoring the volumetric measuring performance of your CMM.

  • Machine checking gauge - no headSpecial calibrated stylus can be used with TP1, TP2, TP20, TP6, TP6A, MIP* and PH50* with suitable adaptors
  • Using the Renishaw MCG, users are able to carry out a 10 - 20 minute interim verification of volumetric accuracy to British standard BS EN ISO 10360-2
  • The results give assurance that measurements taken on the CMM are accurate, or give conclusive proof that servicing or re-calibration work is needed
  • This process is quick and cost effective and a range of pillar heights and arm lengths mean that volumetric accuracy can be checked on both large and small CMMs
  • The probe's stylus slots into the end of what is, in effect, a reference ballbar which travels in a circular path, where radial readings are then taken at 0°, +45° and -45° elevations
  • The range of these readings indicate the volumetric measuring performance of the CMM, repetition of a sequence of readings checks the system for repeatablility
  • Volumetric measuring perfomance is the maximum error between any two points in a plane, over any distance within the full measuring volume
