对于数控设备的任意一根运动的轴而言都有6项误差:线性定位误差、水平方向直线度误差、垂直方向直线度误差、偏摆角、俯仰角、滚动角。目前市场上的激光干涉仪大多都可以测量出以上准确度误差,只是测量的方式方法不同。但是有一项误差测量起来还比较困难,甚至有的同行认为无法测量,这就是本文要探讨的垂直轴滚动角测量解 There are six errors for any axis of motion of the CNC equipment: linear positioning error, horizontal straightness error, vertical straightness error, yaw angle, pitch angle, roll angle. Most laser interferometers on the market today can measure the accuracy of the above error, but the measurement methods and methods are different. But there is an error measurement is still more difficult, and even some colleagues think it can not measure, this is the paper to explore vertical axis rolling angle measurement solution
