摘要：
A new accurate two-probe time domain method is put forward to measure the straight-going component motion error in machine tools. The characteristics of non-periodic and non-closing in the straightness profile error are liable to bring about higher-order harmonic component distortion in the measurement results. However, this distortion can be avoided by the new accurate two-probe time domain method through the symmetry continuation algorithm, uniformity and least squares method. The harmonic suppression is analysed in detail through modern control theory. Both the straight-going component motion error in machine tools and the profile error in a workpiece that is manufactured on this machine can be measured at the same time. All of this information is available to diagnose the origin of faults in machine tools. The analysis result is proved to be correct through experiment.
