Ti-6AL-4V is widely used in the industry for the high strength-to-weight ratio at elevated temperature, its excellent resistance to fracture and corrosion, and biological properties. However, Ti-6AL-4V is hard to manufacture for its reactive chemical properties and low thermal conductivity that causes high temperature on the tool surface. Prediction of the tool temperature distribution from different manufacturing ways, up and down milling, has great significance in predicting tool wear pattern (cutting speed, feed/tooth, and axial depth of cut) in corner milling on temperature of the tool rake face. The tool material used is general carbide and Johnson-Cook plastic model is utilized to model the behavior of the workpiece Ti-6AL-4V. A separate Abaqus heat transfer model is used to analyze the heat transfer process after the tooth disengages the workpiece and before it engages the workpiece again to predict change of temperature distribution during this cooling process. The comparison of the up milling and down milling on the tool temperature is conducted.
