摘　　要：对圆锥凸轮廓面进行数控加工编程时,须预先确定加工刀具的轨迹方程。以在三维空间中建立的圆锥滚子摆动从动件和直动从动件圆锥凸轮机构凸轮廓面统一解析表达式为基础,对数控铣床加工圆锥凸轮廓面所需刀具轨迹方程的建立方法进行了研究,根据所采用的锥形刀尺寸等于或小于圆锥滚子尺寸的情况,推导出相应的刀具轨迹方程统一解析表达式。其结果不仅可作为数控加工圆锥凸轮廓面编程时的基础数学模型,亦可应用于凸轮廓面加工误差分析和加工过程仿真。Before NC programming,the expression of cutter path must be done to determine numerically controlled machining for generating conical cams surfaces.Based on the established analytical profile expression of conical cam with oscillation conical roller follower or with a translating conical roller follower in 3D space,method of determining the required cutter path for cutting conical cam profile using a NC milling machine is studied.The unified analytical expression of cutter path is provided for a tapered endmill cutter,whose size may be identical to or smaller than that of the conical roller.The results are not only the programming base for NC machining the surfaces of the conical cams,but also can be used to analyzing the errors of machining and process emulation of machining.
