摘要: 随着电机微型化,微铣削加工方法在电机生产中使用日趋广泛。受微铣刀强度限制,微铣刀切削刃具有一定圆弧,导致微铣削时出现临界厚度现象。建立二维车削仿真模型对临界厚度现象进行仿真,建立二维铣削模型仿真分析临界厚度下铣削区域温度分布。通过微铣削实验,设置不同每齿进给量,分析临界厚度现象对刀具磨损的影响。

Abstract: With the miniaturization of motor, micro-milling was widely used in micro production. Due to the strength limitation of the micro-milling cutter, the cutting edge of the micro-milling cutter has a certain arc size, which leads to the phenomenon of critical thickness in micro-milling. A two-dimensional turning model was established to simulate the phenomenon of critical thickness, and a two-dimensional milling model was established to simulate and analyze the temperature distribution in the lower milling area of critical thickness. The influence of critical thickness phenomenon on tool wear was analyzed by setting different feed per tooth through micro-milling experiment.

Key words: critical thickness, micro-milling, temperature, tool wear
