In this method, the positioning accuracy and repeated positioning accuracy are tested using the precision linear scale and the reading microscope.

该方法利用精密线纹尺和读数显微镜对数控机床的定位精度和重复定位精度进行检验。

Meanwhile, we found that the latter one is more suitable for measuring machine tools linear positioning accuracy after inspecting a vertical milling machine by using the laser interferometer.

同时，通过对一台数控铣床的测量后，发现激光干涉仪测量法更适合于机床定位精度的快速评定。
