曲面零件五坐标扫描检测路径产生方法研究

摘要

To meet the requirement for the fast measurement for work-parts with complex surface, based on the analysis of the REVO probe system, a method by getting intersection curve formed by part surface and probe surface is presented. The intersection curve is fit to 5-axis scanning measurement. The scanning coordinate measurement is carried out by probe tip, keeping CMM (coordinate measuring machine) axis still.%针对曲面零件对五坐标扫描检测的需求，在对REVO五坐标旋转扫描测头的技术特征进行分析的基础上，提出了适用于五坐标扫描检测路径规划的球面法，通过测尖运动球形包络面与被测工件曲面的相交线来确定检测路径，测量主要由测尖扫描完成，减少测量机的三轴移动，实现高速坐标扫描测量。
