CMM Performance Verification — A Review of Some Existing Techniques
Many different methods have been suggested for checking Co-ordinate Measuring Machines (CMMs) recently. However, almost all are based on measurement of artefact. A small number suggest the use of laser interferometers. This paper tries to identify possible new principles to be used for CMM verification. It presents and discusses techniques chiefly based on non-contacting devices. It is suggested that a new method should be developed in order to improve the performance verification of CMMs.
