无能为力

The conditions to measure accurately and the principles to select parameters of the multi— probes EST method are proposed, and the theoretical research, computer imitation and the experiment on a machine tool prove that these principles and suggestion are necessary and effective. The influence of the initial value errors of the probes, the installation error of the probes system, and the remaining error caused by the radical error motion are analyzed quantitively on the measurement accuracy of the multi—probes EST method. The influence of the error caused by the probe's axes which is not in a plane and the perpendicularity error of the plane which the probe's axes is in to the stational axis are discussed on the measurement results.

结合理论分析，对这些EST方法进行了计算机仿真分析和研究，重点研究了这些方法的应用条件和误差分离精度，所得出的结论是：三测头法EST基本上能实现各项误差的完全分离，适于在位测量使用；二测头法在恰当地选择测头安装角的条件下，可以得到较高测量精度，适于大型零件圆度、圆柱度、径向圆跳动和全跳动的在位测量；对置两测头时域法可以在一定程度上改善单测头法测量精度，但对随机径向误差无能为力；对置两测头频域法存在严重的谐波损失。
