abstract

Materials often behave in a complicated manner involving deeply coupled effects among stress/stain, temperature and microstructure during a machining process. This paper is concerned with prediction of the phase change effect on orthogonal cutting of AISI 1045 steel based on a true metallo-thermo-mechanical coupled analysis. A metallo-thermo-mechanical coupled material model is developed, and a finite element model is used to solve the evolution of phase constituents, cutting temperature, chip morphology, and cutting force simultaneously using ABAQUS. The model validity is assessed using the experimental data for orthogonal cutting of AISI 1045 steel under various conditions, with cutting speeds ranging from 198 to 879 m/min, feeds from 0.1 to 0.3 mm, and tool rake angles from −7° to 5°. A good agreement is achieved in chip formation, cutting force and cutting temperature between the model predictions and the experimental data.
