摘　　要：车床主轴的旋转精度是衡量车床加工性能的一个重要因素。一是车床的主轴旋转精度会很大地影响车床的加工精度;二是随着数控车床的普及,要求对机床的回转精度进行实时测量、实时误差补偿。研究车床主轴旋转精度的测量方法,设计非接触式测量系统来实现机床主轴旋转精度的动态测量,并根据所采集信号初步估计车床主轴的运动情况,具有一定的理论依据及实际应用意义。The rotation accuracy of the lathe spindle is an important factor to measure the machining performance of the lathe.One is that the turning accuracy of the spindle of the lathe will greatly affect the machining accuracy of the lathe;the second is that with the popularization of the CNC lathe,real-time measurement and real-time error compensation of the turning accuracy of the machine tool are required.Studying the measurement method of the turning accuracy of the lathe spindle,designing a non-contact measuring system to realize the dynamic measurement of the turning accuracy of the machine tool spindle,and preliminary estimation of the movement of the lathe spindle based on the collected signals have certain theoretical basis and practical application significance.
