摘　　要：针对紫铜在微铣槽加工过程中毛刺抑制困难的问题,建立了微铣削有限元模型,对毛刺高度进行仿真预测,通过仿真结果分析了主轴转速、进给速度和铣削深度对毛刺高度的影响程度,建立了回归方程并得到最优参数组合,使用直径0.5 mm微铣刀对紫铜进行了微铣削实验。结果表明:回归方程的最大误差为9.02%,验证了模型的有效性和准确性,为实现紫铜微铣削高精度加工提供了参考。In response to the difficulty in suppressing burrs during micro-milling of red copper,a finite element model for micro-milling was established to simulate and predict the burr height.The effects of spindle speed,feed rate,and milling depth on burr height were analyzed through simulation results,and the optimal parameter combination was obtained by fitting a regression equation.A micro-milling experiment was carried out on red copper by using a 0.5 mm micro-milling cutter.The results show that the maximum error of the regression equation was 9.02%,verifying the effectiveness and accuracy of the model,and providing a technical basis for achieving high-precision micro-milling of red copper.
