MODELING AND SIMULATION OF CUTTING TEMPERATURE FIELD WITH SERRATED CHIP
A finite element model is established to investigate the distribution mechanism of serrated chip temperature field in High Speed Cutting (HSC).Zerilli-Armstrong plasticity model and Cockcroft-Latham crack model are adopted as workpiece material model and failure criteria respectively.Zorev model automatically identifying sliding region and sticking region is used to define the interaction between tool rake face and serrated chip.Material cutting process is simulated using the established model, and the temperature distribution is analyzed, then the distribution mechanism of serrated chip temperature field is discussed.The simulation results show that high temperature area of the process is evenly distributed along the two sides of adiabatic shear bands, the second high temperature zone is formed near the chip and tool contact point.
