STUDY OF ROUNDNESS ERRORS MEASUREMENT ON CMM USING A SEPARATION METHOD

The accuracy of roundness measurement on CMM is in majority affected by the probe errors and geometric errors related to the machine axes. The separation technique is an approved method for decoupling the probe errors from other source of errors. This paper presents a novel application and a study of the separation method, to measure the roundness errors separately to the probe errors and machine errors. The proposed approach has been tested and validated using several virtual machines.
