The Numerical Simulation Technology in the Cutting Process of Alloy Steel AISI4340

Using the finite element analysis software ABAQUS, simulation experiments on physical nonlinearity, geometric nonlinear, nonlinear finite element, elastic-plastic in the cutting process are conducted, which realize the separation of chips and working piece combined with material failure criterion, shear failure, adaptive grid technique in ABAQUS. Meanwhile, the stress field, strain and temperature field and cutting force in the cutting simulation are obtained consistent with cutting theory.
