摘要

基于四轴数控铣齿机变性法加工弧齿锥齿轮小轮的几何原理和机床运动学原理,推导了粗铣小轮过程中切削层瞬时切削面积的计算公式。采用传统切削力模型,建立了变性法加工弧齿锥齿轮小轮的铣削力模型,编写了铣削力仿真程序,并设计了验证方案。结果表明:采用不同切削用量时,考虑了传动效率的主电机切削功率计算结果与主电机变频器输出功率测量结果幅值基本在同一区间范围内,时间间隔一致,从而间接证明铣削力模型的有效性。
        Based on the modified-roll method geometry theory and 4-axis CNC machine kinematics principles,the instantaneous cutting area formulas of the spiral bevel pinion rough milling were deduced.According to the traditional milling force model,the spiral bevel pinion rough milling force model based on the modified-roll method were presented,the milling force simulation programs were composed and the experimental schemes were designed.The experimental results show that the amplitude of the main motor cutting power and the transducer output power are almost in the same interval and the time intervals are the same.And the rough milling force model herein can guarantee a certain precision.
