Abstract: Numerical cutting modelling gives access to thermo-mechanical field such as stress, strain and temperature that are difficult to obtain through experiments, thus provides a unique insight and helps to improve design quality and shorten design cycle. Chip separation is one of the most important issues in cutting simulation because of its significant influence on chip formation, stress and temperature predictions. Modelling of an orthogonal cutting process using ABAQUS/explicit is presented. Two kinds of chip separation approaches are compared, a partial damage zone (PDZ) and an Arbitrary-Lagrangian-Eulerian (ALE) based approach, with the aim to characterize the effect on chip formation, cutting force, temperature and residual stress. ALE and PDZ methods predict the similar cutting force and temperature results, and they also predict different chip formations and residual stress profiles. The predictions are analysed and possible reasons are discussed.
