In order to explore the optimal turning parameters for different surface roughness requirements of 2Cr13 stainless steel materials, the center composite method was used to establish the turning test matrix,and the influence law was analyzed based on the turning test results, and the surface roughness prediction model was obtained by using the response surface method. Roughness Ra0.2 μm、Ra0.4 μm and Ra0.8 μm are the targets, and the optimal turning parameters to meet different surface roughness requirements are obtained by using the response surface optimization algorithm, and the optimization results are verified by actual machining. The results show that : The obtained optimal turning parameters all meet the surface roughness requirements and have good engineering practice significance.
