摘    要：本文以仿形磨削法磨削正方形刀片的周边为例,分析了多边形轮廓表面的生成原理,导出了仿形凸轮廓线方程,并由此得出了一种快速设计仿形凸轮的简捷作图法。

Abstract: Compared with the methods of dividing grinding and copying grinding in the similitude of insert shape with uniform centre distance, the method of complete copying grinding for peripheral shapes of cemented carbide indexable inserts has many remarkable advantages, such as higher production efficiency, better grinding accuracy, simpler construction of the grinding machine, etc. This paper describes the principle of copying grinding for peripheral shapes of cemented carbide indexable inserts in detail and derives the mathematical model of the master cam profile and presents a simple and fast drawing method of the master cam design.
