摘　　要：本文应用曲线拟合法对测量信号进行拟合,识别并保留了一次误差运动,正确消除了测量球的偏心,从而得到包含一次误差运动在内完整的误差运动。并用LSC中心进行误差评定。编制了操作简便、容易掌握的实用软件。In this paper, the curve - fitting method is used for fitting the measuring signal distinguishes and retains the first harmonic component; eliminates correctly the eccentricity of sphere, thus obtains the complete spindle error motion included the first harmonic component, and evaluates the error of spindle rotation with the center of LSC, and opens up a useful computer software which is easy to be operated and known well.
