Simulation Research on the Metal cutting process
The three-dimensional explicit dynamic analysis of metal cutting process is done using the non-linear finite element software LS-DYNA.In the timite element model,8-node 3D solid element based on one-point integration Lagrangian formulation is adopted,metal material is modeled with Johnson-Cook constitutive model,chip separation is simulated using the material failure criterion of Johnson and Cook proposed and combing the failure element deletion method,friction model of chip-tool contact interface is developed to simultaneously account for sticking and sliding situation.Through explicit analysis,rake angle,cutting depth,and cutting width on the shape of the chip influence are obtained.
