| 摘 要： | 基于三坐标测量机的边界扫描方式，提出一种在工件型面上直接采点的凸轮快速测量方法。基于点方法生成B-样条曲线函数拟合测头中心轨迹，构造偏置曲线函数，对球形测头进行半径补偿，并利用UG／OPEN GRIP软件生成凸轮的实际轮廓线和升程曲线。试验结果表明，该方法能高效、准确、方便地实现凸轮检测。

| Abstract: | Based on CMM's boundary-scan mode,a quick measuring method for cams by direct collecting point data on workpiece surface was presented. The B-spline curves based on the point method is created to fit the trace of center of ball probe,and the bias curve function is constructed to compensate the probe radius,and the actual contour and lift curve of cam is generated by using UG/OPEN GRIP. The test results show that cam measurements can be carried out efficiently,accurately and conveniently with this method. |
