This paper is based on optimization theory,takes Bearing ring thin-wall parts for example,and makes pro-cessing quality as optimization aim. Processing parameters of the thin-walled bearing ring are optimized, and the best cutting parameters of the cylindrical surface are obtained in the semi-finishing process and finishing process. The surface roughness is 0.38 um of the processed parts. The paper uses Ansys software to simulate the machining process of bear-ing ring and the parts deformation is 0.000034mm. The results can meet the shape tolerance requirements of bearing rings parts. This paper provides theoretical basis and technical approach of increasing efficiency of machining bearing rings and similar thin-walled parts.
