Abstract:The cutting force is the main parameter in characterization of machining process,which is one of the important physical quantities reflecting the machining state,and the cutting force directly affects the machining conditions and machining surface quality.Based on the finite element analysis (FEA) software AdvantEdge FEM,the orthogonal test was designed to feed, cutting depth,cutting speed,turning tool rake angle,turning tool relief angle cutting parameters for the five independent variables and four levels.The process of highspeed turning of 3Cr13 stainless steel was simulated by using two dimensional (2D) FEM to explore influence law of each independent variables on cutting force. By taking the radial cutting force at minimum as objective, the method of analysis of variance was used to obtain the optimal combination of every cutting parameter.The results show that the maximum effect on the radial cutting force is cutting depth,and the minimum effect on the radial cutting force is turning tool relief angle.In the given cutting conditions,the optimal combination of the radial cutting force is the hour to feed 019 mm/r,cutting depth 03 mm,cutting speed 500mm/min,turning tool rake angle of 19 °,and turning tool relief angle 7°.
