Numerical Simulation Of Stress Field And Temperature Field Of Two-dimension Metal Cutting

Based on the analysis of the process of free orthogonal metal cutting, the theory of elastic-plastic distortion and temperature field was discussed. Yield rule, intensify rule, fluxion rule, types of contact and diathermanous model of metal cutting were also analyzed detailedly. The FEA model of stress field and temperature field of free orthogonal metal cutting were established by the fundamental idea of FEA. State nonlinear, material nonlinear and geometry nonlinear thermal-stress coupling were analyzed by FEA technology. The separate criterion of chip and dispose of contact types were research emphatically. Stress field and temperature field of free orthogonal metal cutting are simulated precisely and vividly through the technology of numeric imitation which based on the general international large software ANSYS. Moreover, the form process of the chip was analyzed. The distribution stress field , temperature field of initialized and steady state were got. There were same trend of temperature distribution in rake plane and shear plane, and the feasibility of numeric simulation through was validated through comparing the result of experiment with simulation result.
