1.前言加工形状的精度一般取决于机床的精度和加工条件。在精车加工中,车削部分就是最后的表面轮廓。关键问题是如何减小机床各零件的误差和装配误差,平衡各部分零件的误差分布。另一方面,为了得到更高精度的表面轮廓,可以采用研磨或抛光。在最后阶段,一面加工一面重复测量其表面,轮廓精度取决于测 1. Introduction The accuracy of machining shapes generally depends on the accuracy and machining conditions of the machine. In finishing, the turning part is the final surface profile. The key problem is how to reduce the error of machine tool parts and assembly error, balance the error distribution of each part. On the other hand, in order to obtain a more accurate surface profile, grinding or polishing can be used. In the final stage, the surface is measured repeatedly while machining and the contour accuracy depends on the measurement
