MCG machine checking gauge

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

Special 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

Renishaw’s machine checking gauge (MCG) provides an easy way to monitor the volumetric measurement performance of your co-ordinate measuring machine (CMM). The MCG is an effective complement to existing standards for CMM verifi cation and can be used as an interim checking gauge in accordance with international standards BS EN ISO 10360-2.

MCG tools is an Microsoft Excel workbook that manages the machine checking gauge (MCG). MCG tools allows the user to generate a DMIS part program in order to execute the MCG test on a co-ordinate measuring machine (CMM). It can then import the MCG data to analyze and identify whether geometrical errors exist on the CMM. Also, the results from every MCG test can be archived in order to follow the evolution of the geometry of a CMM over time.
