弧面分度凸轮加工刀具轨迹修正分析

Analysis of Tool Path Modification in Globoidal Indexing Cam Machining

提出了对传统范成法加工的刀具轨迹进行修正来加工弧面分度凸轮的原理和实现方法,该方法是对传统范成法的发展,实现了范成法的单侧面加工。既克服了传统范成法加工的不足,提高了弧面分度凸轮表面加工质量,又使得凸轮机构的啮合特性得到改善。

A new tool path control method was presented, it modifies the tool path of traditional enveloping method, realizes one - side machining of the globoidal indexing cam. The new method overcomes the defects caused by traditional enveloping method, improves the machined surface quality and the meshing characteristics of the cam mechanism.
