In the process of verifying calibration proofreading template of the coupler,there are problems such as large sdeviation in the touch angle,uneven measurement force when measuring the coordinates of feature point,and long pro-gramming time when using manual marking for programming.By utilizing the function of automatically identifying fea-tures of the software in the three-coordinate measuring machine,the measurement process is planned based on a three-dimensional data model,and an automatic measurement program is developed to achieve automatic measurement of calibration template of the coupler.A comparative analysis of the process and results of manual measurement and auto-matic measure ment shows that both manual measurement results and automatic measurement results meet the require-ments;the repeatability test of both shows that the results of automatic measurement are more stable and accurate.
