GH4169 叶片表面粗糙度和残余应力的砂布轮抛光工艺参数区间优选

In order to obtain the ideal polishing surface roughness and polishing surface residual stress of GH4169, a double objective optimal interval division method for polishing process parameters was proposed, and five-factor three-level polishing orthogonal test was designed; According to the standard deviation of the test results, the influence weight coefficients of the process parameters on the optimization objectives were calculated, and multiple optimization objectives were transformed into a comprehensive optimization objective. The change mechanisms and trends of the optimization objectives with the increasing of process parameters were analyzed via tendency chart. The optimal process parameters were determined with the proposed method, and its reliability was further verified via an experiment.
