Research on Cutting Temperature Using FEM Method while Machining Titanium Alloy TC4

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 while machining titanium alloy TC4. The temperature of cutting zone was measured by natural thermocouple and compared with the simulated results.
