In this paper, using the method of single factor experiment, set the test parameters of 300M steel through AdvantEdge software broaching process simulation test, simulation results for the finishing, analyzed the influence of broach rake angle and relief angle, tooth lift and cutting speed on cutting force and cutting temperature in the process of broaching, observed the cutting temperature in the broaching process of regional changes, through the analysis, provides theory basis for reasonable design of the broach. The results show that the tooth lift has the greatest influence on the cutting speed, and the tooth lift and cutting speed have the greatest influence on the cutting temperature.
