ADVANCES IN NUMERICAL SIMULATION TECHNOLOGY FOR CUTTING PROCESS

Recently, the finite element method (FEM) hasbeen widely applied in cutting process, and plays animportant role in the investigations of technicalparameters and chip mechanism. This paper reviews thestate-of-the-arts in this field, discusses some keyaspects in the FEM simulation of cutting process, includingchip plastic formation, thermo-mechanical coupling, thecontact and friction between workpiece and tool, chipseparation criteria, and residual stress and strain. Atlast, the new trends of FEM simulation for cutting processare predicted.
