In order to solve the problem of tool wear aggravation caused by large cutting force and high cutting temperature during the cutting process of GCr15 hardened bearing steel, the texture was preset on the surface of the workpiece. The finite element simulation and orthogonal test were combined to simulate the cutting process, and the optimization analysis was carried out by using the signaltonoise ratio analysis method. Range analysis and variance analysis were used to determine the optimal cutting parameter combination and the influence of cutting parameters on cutting force and temperature. The cutting simulation results show that cutting speed of 120 m/min, feed rateof 0.05 mm/r and cutting depth of 0.1 mm are the optimal cutting parameters combination. The cutting simulation of GCr15 bearing steel with surface texture was carried out under the condition of optimal cutting parameters, and the simulation results of cutting force and cutting temperature were obtained. The cutting simulation results of workpiece with and without surface texture were compared. The results show that the cutting force and cutting temperature of the workpiece with surface texture are reduced effectively, and the surface texture is beneficial to reduce tool wear and improve tool life.
