Application of Error compensation Technique for NC Machine ToolsCompensating Technique for Improving On line Inspecting Accuracy

文章利用在机测量运动链分析，提高测头球心的定位精度；同时以特征分析法来处理测头的内部误差。通过补偿前后与三坐标测量机的实验数据对比，结果表明补偿效果良好。

The manufacture proceeding is of high integration and flexibility. It is emphasized how to percerve high efficiency of manufacture system and reduce the waste products. The technique of on line ispection is one of the most important meanings for monitoring the cutting procedure. The kinematics chain of on line inspection is discussed, so as to enhance the positioning accuracy of the ball center of a probe, meanwhile, the system error of a probe is treated by means of the method of feature analysis. Compared the testing data with and without compensation with measured data on CMM, the result shows that the compensative effect is good.
