Simulation of Cutting Temperature Distribution while Machining Titanium Alloy TC4

Dong Liu, Run-yi Liu, Fang Wang


Titanium alloys are widely used in aerospace industry due to their excellent mechanical properties. Because of their low thermal conductivity, high chemical activity, large friction coefficient and so on, such problems occur during the cutting process as high cutting temperature, large specific cutting force and serious tool wear, leading to low machining efficiency. The titanium alloys classified as difficult machining materials. The finite element method is the new method to study the machining process. The FEM method was used to simulate the cutting temperature distribution while machining titanium alloy TC4. The temperature distribution of cutting tool and workpiece-chip were simulated and the simulation results were analyzed.
