摘　　要：切削用量的选择对刀具耐用度、产品的加工效率以及加工质量等都有直接影响。为选取合理的切削用量,以最大生产效率为目标,建立铣削加工优化模型。结合实际加工中不同约束限制,采用改进遗传算法(Multi-Island GA)对目标函数寻优求解。将优化后的结果与切削用量手册经验值相对比,切削用量的选取得到了有效改善,并提高了铣削加工的生产效率,且优化结果验证了算法的可行性。The choice of cutting parameters has a direct influence on tool life, products efficiency and quality. In order to select reasonable cutting parameters, taking the maximum productivity as the goal, a milling optimization model was constructed. Combined with the different constrains in practical processing, the improved genetic algorithm （Multi-Island GA） was used to find the optimal so- lution of objective function. Compared the optimized results with the empirical value of cutting manual, the selection of cutting parame- ters is improved effectively, the production efficiency is also improved, and the optimization results verify the feasibility of the algo- rithm.
