Abstract: A new diagnostic method and system is put forward in this paper on the compensation motion error. This new method transfers the motion error to the nermal direction of out gear to be observed. Unlike the traditional method, the new method does not need the reference system usually made up by precision element, but uses a workpiece which has been cut by the measured machine tool as a measurement element. According to the principle of error correlation and error separation, compensation motion error of machine tools and the waviness error of gear tooth can be evaluated and the main errors can be found. Some examples are given at the end of this paper.
