NC Machining of Conical Cam Mechanism with a Translating Conical Follower

应用单参数曲面族包络面理论分析和研究圆锥滚子直动从动件圆锥凸轮机构,导出了圆锥凸轮廓面的数学表达式 以该表达式为基础。

The research presented in this article introduces the profile determination of conical cam with a translating conical follower mechanism based on the theory of envelopes for 1 parameter family of surfaces. The analytical expression of cam profile is established once the follower motion program has been given. Using the obtained analytical profile expression, the required cutter path is provided for a cutter, whose size may be identical to or smaller than that of the conical follower.
