评价精密机床要求测量主轴回转精度,对此 CIRP 统一文件给了必要的指导。本文把从很简单到很复杂的测量主轴回转径向误差运动的各种新方法作一介绍。以便工业单位能根据自己有的仪器来选择适当的评定误差的方法。这些方法绝大部份的特点是很容易评定误差的。在所介绍的方法中主要的原理是通过不同的模拟或数字法窄频带剔除相应于回转频率的讯号分量。同时也给出与已公布的方法的相对比较。
Evaluation of precision machine tools required to measure the spindle rotation accuracy, the CIRP unified document gives the necessary guidance. In this paper, a very simple and complex method of measuring radial movement of the spindle rotation error of the various new methods are introduced. So that the industrial units can choose the appropriate method of evaluating the error according to their own equipment. Most of the features of these methods are easy to evaluate for errors. The main principle in the method described is to strip out the signal component corresponding to the swing frequency over a narrow band of different analog or digital methods. It also gives a relative comparison with published methods.
