摘要
三坐标测量机对空间任意直线测量时 ,如果将其标准尺用线性球列代替 ,使线性球列空间化 ,再通过特定的分析和处理 ,求得空间线段的测量误差 ,实现对三坐标测量机的精度检定。文中对该检定方法进行了深入细致的精度分析与计算 ,检定不确定度评定结果表明 :该检定方法符合坐标测量机检定规程的要求 ,并且具有较高的检定精度 ,不失为有关系统提供了一种可操作性强。
3-D coordinate measuring machine may be used to measure the arbitrary straightness in space, 1-D ball array is expanded into 3-D space and replaces the standard scale, though some special analysis and processing, the measurement errors of spatial straightness are achieved, then the precision verification of 3-D CMM can be realized. In this paper, careful analysis and computation on precision of the new method are finished. The verification results on uncertainty show that the approach described in the paper is conformed to verification regulation of CMM and it is of higher accuracy. What is more, it is a simple, convenient, low cost and effective method for some related system.
