Abstract
Aiming at the problem that deformation caused by cutting force in the cutting process of A357 aluminum alloy, a two-dimension cutting simulation was established based on ABAQUS. The curves of chip, cutting force and stress under different cutting conditions were obtained by using Johnson-Cook constitutive equation. The finite element simulation was applied to further analyze the effects of different cutting conditions on chip, cutting force and stress. The simulation results show that the cutting force increases with the increase of cutting speed and increases with cutting depth in the experimental parameters range, it also leads to poor cutting quality. As the cutting length changes, the fluctuation of cutting force also increases and affects the overall quality of the workpiece.
