Computer simulation of metal cutting process on the elastic-plastic deformation

Computer simulation of the metal cutting process has been done for von Mises yielding criterion and Prandtl-Reuss flow rule. Based on the physical model, mathematical modeling is brought forth with modified lagrangian matrix equation. Super-over-relaxation method is applied for solving the elastro-plastic deformation problems. Programs for grid plotting, calculating and graphically-reporting are edited and successfully executed. Experiments have shown that the simulating system is able to supply the reliable and acceptable decision-making of the machining design for technicians or workers.
