Based on finite element analysis software AdvantEdge,it simulates the cutting process of 7050 aluminum alloy materials,analyzes the effects of different cutting parameters on the residual and temperature of the workpiece surface. The simulation results show that the surface of workpiece is the residual compressive stress,and the subsurface is residual tensile stress. The cutting parameters have less influence on the maximum residual stress depth. The amount of feed has the greatest influence to the residual stress on the surface of the workpiece,the cutting speed is the second,the depth of cutting is the smallest. The cutting temperature also shows some regularity with the change of cutting parameters.
