Influence of Tool Geometrical Parameters in High Speed Cutting of Aluminum Alloy

Tool geometrical parameters had great influence on the cutting. The orthogonal finite element model was established. The model was used to simulate the influence of the geometrical parameters (rake angle, clearance angle, radius of tool tip) on the high speed cutting of aluminum alloy 7050T7451, and to investigate the influence of these parameters on the chip formation. In the same cutting condition, the cutting force experiment was carried out. A good agreement between cutting force of simulation and experiment was achieved. The results of simulation were proved to be correct. The study of geometrical parameters provided the base for the selection and optimization of tool in cutting of aluminum alloy 7050T7451.
