Research of Distribution of Temperature Field in Process of Shaping

The cutting is an important machining technology, in which is belong to nonlinear large deformation, involving material nonlinear, geometry nonlinear and original bug, the thermal energy coupling question, and the nonlinear boundary condition, and so on. For the processing of metal cutting, using the large-scale commercial finite element theory, the coupling finite element model is established the consideration metal orthogonal cutting thermal energy based on the hot elastoplasticity finite element method. Analyzing the scrap processing simulation and so on swarf separation criterion, auto-adapted grid key aspects. Depending on the established the finite element model, it obtained the distribution laws of the temperature field and displacement field. The study results can give a theoretical basis for selecting the cutting tool shape, preferable surface. The research will develop the new cutting tool material, at the same time reduce the experimental cost.
