摘　　要：为获得理想的高温合金GH4169铣削表面粗糙度,设计GH4169铣削正交试验,建立表面粗粗度预测模型,利用相对灵敏度分析工艺参数对表面粗糙度影响的主次顺序,通过趋势图分析工艺参数对表面粗糙度影响机制及影响趋势;提出工艺参数优选区间确定方法并获得铣削工艺参数优选区间;采用遗传算法获得优化的铣削工艺参数组合。铣削实验结果表明:优化工艺参数不仅能获得较小的表面粗糙度,而且减小了刀具磨损。In order to obtain the ideal milling surface roughness of high temperature alloy GH4169,the prediction model of surface roughness was established based on the orthogonal milling experiment of GH4169.By using the relative sensitivity,the influence order of the technological parameters on the surface roughness was analyzed,and the influence mechanism and influence trend of process parameters on surface roughness were studied with trend chart.The determining method for the optimum range of process parameters was put forward and the optimum range was achieved.Genetic algorithm was applied to gain the optimized combination of milling process parameters.The result of milling experiment shows that the optimized milling parameters can not only obtain smaller surface roughness,but also reduce tool wear.
