FEM has become a powerful tool for predicting cutting process variables, which are difficult to obtain with experimental methods. In this paper modeling techniques on chip formation are discussed. Because of the limitations of Lagrangian and Eulerian approaches, a modeling method based on ALE (Arbitrary Lagrangian Eulerian) approach by using the commercial FEM code ABAQUS is proposed to simulate the chip formation process. It consists of three chip formation analysis steps, i.e. initial chip formation, chip growth and steady-state chip formation. With this modeling method, the entire chip formation process in high speed turning stainless steel 2Crl3 with carbide tools is simulated. And the predicted cutting force and temperature are compared with experimental data. And the result testifies the validity of the modeling method.
