| Abstract: | In order to analyze the influences of the different tool's shape and surface conditions (such as different coated and material) and their interaction on the cutting temperature, a coupled thermo-mechanical finite element analysis (FEA)model of plane-strain orthogonal metal cutting process is constructed, and 16 simulation cases with 16 different types of tools, which cover 4 rake angles, - 10°, 0°, 10°, 20°,and 4 friction coefficient values, 0, 0.1, 0.2, 0.3 in the same cutting condition (cutting depth and cutting speed)have been performed. Finally the simulation results are analyzed according to the variance analysis method (VAM)of orthogonal array designs (OADs), the relationships between the rake angle, tool-workpiece interface's friction coefficient and their interact effect to the maximum temperature value and the temperature field of the chip are obtained. This result has some instructive meaning to analyze the causes of the cutting temperature and to control the maximum temperature value and the overall temperature field in the metal cutting process. |
