摘要
阐述了用三坐标测量机测量面对面垂直度的原理,分析了影响测量精度的主要因素。采用最小条件法拟合基准平面,以减小基准平面拟合误差;准确测量被测平面内一段长度,按比例放大至整个平面,以减小被测平面长度误差;通过大量实验和对比分析,确定用等间距法测量平面的最佳采点数,以减小采样误差。
The measuring principle of plane-to-plane perpendicularity with a coordinate measuring machine is described, and main factors that influence measuring precision are analyzed. Minimum area method is applied to eliminate datum plane fitting error. In order to diminish the length error of measured plane, the tactics of measuring some part of plane and then scale to the whole plane is employed. Through large quantity of experiments, the most appropriate number of points for measuring plane is determined to reduce sampling error.
