Abstract
This paper analyzes the deviation of concentricity measured by coordinate measuring machine (hereinafter referred to as CMM). We can select a better measurement system and sampling strategy, so as to improve the accuracy of concentricity measured by CMM to the greatest extent. It is the first time to put forward the concept of uncertainty in measuring concentricity with different CMM under specific conditions. This paper analyzes the advantages and disadvantages of various flexible measurement methods, also point out the calculation defects of common axis method and straightness method and the possibility of misjudgment. Finally, the author summarizes the experience of measuring concentricity with CMM.
