Study on the effect of tool inclination angle in machining process based on three three-dimensional thermo-elastic-plastic model

摘要：

Based on large deformation theory and virtual work principle, a coupled three three-dimensional (3D) thermo thermo-elastic elastic-plastic finite element model (FEM) was constructed to simulate the high speed cutting process of Al Al7050 7050-T7451 T7451. The mechanical properties of workpi he workpiece ece material under conditions of high temperature and high strain rate were defined in the model model. A . Shear friction model was involved at the interfaces of tool tool-chip, tool tool-workpiece. Based on the model, different 3D machining FEM with different inclination angles were established, and distributions of stress, strain and temperature were achieved. Further more, the effects of inclination angle on the chip curl curling ing direction, chip flow angle, cutting force and cutting temperature were studied.
