摘　　要：借助速度瞬心的性质,针对摆动滚子从动件盘形凸轮,推导建立了一套既可计算凸轮廓线又可直接计算加工凸轮时的刀具中心轨迹的解析公式。公式形式简单,推导过程简洁明了,为此种凸轮廓线的设计和刀具中心轨迹计算提供了一种新方法。With the help of the property of instantaneous speed center and being aimed at the plate cam with a roller-swinging-follower,the author has established a set of analytic formulas for calculating both the borderline of the cam and the cutter central path. The formulas is simple and their deriving process is concise and easy to understand. And in this paper,the author offers a new method for the design of the borderline of the cam and the calculation of the cutter central path.
