提出一种基于数控转台和坐标测量机的测量方法，以涡轮转子为研究对象，实现其叶片分度误差的自动数字化测量。通过建立分度角模型，进行干涉分析，并提出一种闭环反馈测量算法，从而避免测针与叶片之间发生干涉。试验结果表明，该方法的扩展不确定度为18.14″，测量周期为1.5h/件。

Based on the numerical control running-platform and coordinator measuring machine, an automatic digital method is developed to measure the centripetal angle error of turbine rotor. The mode of centripetal angle is set up, the analysis of intervene problem is put forward, and an algorithm called closed loop feedback is designed to avoid the intervene between the probe and vane. The experimental results show that the expand uncertainty is 18.14″, and the measuring cycle is 1.5 hour per piece.
