摘要：针对带锯条铣齿加工常用的三段式加工工艺中切削量设计与精度要求不符的现象，综合考虑了成型铣刀刃口形状、空间运动形式以及锯齿形成的不同阶段，提出了以异形刃口离散的方法建立刃口切深与刃口作用长度关系模型。并在此基础上建立了带锯条成型铣刀单个刃口的切削量计算模型。以单圆弧过渡齿形为例，代入实际参数进行模拟计算，获得了带锯条铣齿加工过程中切削量以及刃口切削体积变化规律。结合带锯条实际加工对效率和精度的要求，提出了增加铣齿分段数量和控制吃刀量及切削体积的优化工艺方向。

Abstract:This paper is aimed at the traditional process of three segments in the band saw blade milling process whose cutting volume designing is mismatching with precision requirements.By discretizing tooth profiles，the relationship between the depth of the edge cutting into bimetal blade and the acting length on the edge has been established.Then，the edge shapes，motion state and teeth forming progress have been considered to build the calculation model.Taking the tooth profile with single transition fillet for example，the changing way for the cutting depth and the cutting volume on the single cutting edge are found under real parameters.According to the efficiency and precision requirements for the band saw blade milling，the optimal process of adding more segments with different feed rates and controlling the cutting volume is proposed.
