【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.更多还原
