摘　　要：针对数控加工复杂曲面零件的加工误差评定问题,采用离线检测方案坐标测量法进行评定.利用超高精度三坐标测量机进行检测,可以获得测量点的坐标值.建立复杂曲面加工误差坐标测量的数据处理模型,再进行计算,得到复杂曲面加工误差的大小及其分布.通过一个复杂曲面的零件实例分析证明,提出的坐标测量法是一种快速而有效的评定复杂曲面加工误差的方法.Aiming at machining error in machining complex surface parts with CNC machine tools, the off-line detection scheme coordinate measuring method is used. Coordinate measuring point values can be obtained through inspection with high precision coordinate measuring machine. The values and distribution of machining errors of complex surfaces can be obtained by using the data processing model, which is based on the measurement of complex surface profile errors. The coordinate measuring method is proved to be a fast and effective method to evaluate the machining errors of complex surface by analyzing the part with a complex curved surface.
