摘　　要：针对10Ni3MnCuAl塑料模具钢进行切削试验,探索不同切削参数对表面粗糙度的影响规律。采用多元回归方法,建立了10Ni3MnCuAl塑料模具钢高速铣削表面粗糙度预测模型,用F、t检验法验证模型的显著性。基于遗传算法,以指定的表面粗糙度值为约束条件,材料去除率Q为目标函数进行工艺参数优化,对10Ni3MnCuAl塑料模具钢高速铣削加工切削参数的选择具有一定的指导意义。In view of the cutting experiment of 10Ni3MnCuAl plastic die steel, the influence of different cutting parameters on the surface roughness is explored. By using multiple regression method, the prediction model of surface roughness in high speed milling of 10Ni3MnCuAl plastic die steel is established, and the significance of the model is verified by F and t test. This paper specifies the surface rough degree value as constraint conditions, and specifies the material removal rate Q as objective function to optimize the process parameters based on genetic algorithm. The results has certain guiding significance on parameter selection in high speed milling machining of 10Ni3MnCuAl plastic die steel.
