摘　　要：为解决旋转工作台在装配过程中产生的安装误差,旋转轴与坐标测量机Z轴不平行,因而造成整体检测精度不够这一难题,提出了旋转轴空间位置参数标定的新方法:设计专用标定工装,通过找正和测量标定工装的基准面和基准孔特征要素,得到旋转轴所在空间直线方程,从而实现旋转轴空间位置参数的标定。实验结果表明该方法简单、高效,基于该工装的旋转轴空间参数标定方法与数据整合算法适合航空发动机叶片高精度的检测。The error of turntable would be produced in the process of parts assembly and cause axis of the turntable and Z-axis of coordinate measuring machine（CMM） not parallel. A calibration method of axis position parameters is introduced to solve the problem of precision decline. The specialized calibration frock was designed. The space linear equations of axis was got through aligning and measuring reference plane and reference hole of the calibration frock,which achieve calibration of axis position parameters. The experiment results showed that the method is simple and efficient and can be used in precision measurement for aero-engine blade based on the method of space parameter calibration of axis and data integration algorithm.
