Based on thermo-elastic-plastic FEM,the finite element model of orthogonal cutting was established in DEFORM3D codes.Key factors affecting the cutting simulation such as constitutive relation of workpiece,local automatic remeshing,the criterion of chip separation and the friction between tool and chip were considered during the process of modeling.The equivalent stress distribution of workpiece during the cutting process was studied.The qualitative relation between cutting speed and workpiece residual stres...
