Optimization Reserch on High Temperature Alloy GH4169 Milling Process Parameters for Surface Roughness
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.
