课题

The error source of CMM is complex, and the current main research is its geometric error. In the paper, 21 items of geometric error are measured accurately, simply and fast with the 2-D laser interferometer and four quadrants photo detector. The measurement gets rid of measuring so many lines and several diagonal lines in linear displacement method, and also solves the question that error measure of large-scale CMM can not be measured with 1-D ball array and ball plate conveniently.

坐标测量机的误差源纷繁复杂，当前主要研究的是其几何误差，课题中研究了一种采用二维激光干涉仪和四象限光电探测器相结合的测量方法，对三坐标测量机的21项几何误差进行了准确、简便、快速的测量，摆脱了线位移法测量直线过多且包含多条对角线测量的弊端，同时也解决了一维球列和球板不方便检测的大型测量机的误差检测问题。
