超长数控丝杠磨床精度检测及其不确定度分析

The Accuracy Measurement and Its Uncertainty Analysis of Ultra-length Lead-screw Grinding Machine

介绍了用激光干涉仪检测超长数控丝杠磨床定位精度、重复定位精度的方法,并通过建立数学模型对这种测量方法的不确定度进行了分析。

This paper mainly discusses the measuring method of the positioning accuracy, and the repeatability of ultra - length CNC lead - screw grinding machine, and by the way of mathematic ally modeling, makes an analysis on the measuring uncertainty of this method.
