【Abstract】 The 3D thermo-mechanical coupling model in bevel milling process was used to perform a numerical simulation of the milling process of multi-hardness spliced quenched steel, so that the cutting force and cutting temperature during milling were obtained. On this basis, the impacts of cutting speed,cutting depth and angular tilt to the cutting force were analyzed. The 3D numerical simulation of the cutting process could provide a reference for the selection of the process parameters and the rational determination of the geometrical parameters of the cutting tools during milling of the multi-hardness quenched steel.更多还原
