ABSTRACT: With the development of high-tech, the construction of intelligent production lines, and the advancement of the Industry 4.0 era, the demand for high-end products is increasing. As China’s requirements for part machining accuracy are continuously upgraded and the scale of mass production expands, the demands for the accuracy and efficiency of part measurements are becoming higher. As a high-precision inspection equipment, the coordinate measuring machine (CMM) fully meets the requirements of modern industry in terms of inspection accuracy and efficiency. Therefore, using CMMs for part inspection is imperative. Currently, CMM inspection is one of the main methods for detecting dimensional tolerances, form tolerances, location tolerances, and orientation tolerances of parts. Its advantages are high accuracy, good repeatability, high efficiency, and low cost. This paper analyzes the measurement results of flatness of planes themselves, parallelism between planes, perpendicularity between cylinders and planes, and position tolerance between cylinders and planes and between cylinders in rotary parts. It summarizes the main causes of errors and provides suggestions and recommendations for subsequent inspection directions.
