The aim of this paper is to compare the predicting ability of the orthogonal cutting models developed by three commonly used finite element softwares, namely commercial explicit dynamic code Abaqus/explicit, Thirdwave AdvantEdge and implicit finite element codes Deform 2D. In all proposed models, the chip formation was simulated through adaptive remeshing and plastic flow of work material around the round edge of the cutting tool. Therefore, there was no need for a chip separation criterion which made the physical process simulation more realistically. Predicted cutting, feed force and shear angle were compared with experimental results. In addition, the effect of friction coefficient on the chip morphology was investigated as well.
