What is New CMM Performance Evaluation Tests about?
This document proposes modifications to tests for evaluating Coordinate Measuring Machine (CMM) performance. It argues that current standards allow manufacturers to publish overly optimistic specifications by testing under ideal conditions unlike how most users operate. The proposed tests require manufacturers to specify performance using a steel artifact with normal thermal expansion, and to use an offset probe. Test results on two machines show the proposed tests reveal larger errors than the current test
