Study on the Cutting Temperature of Serrated Chip while Machining Titanium Alloy TC4

Abstract

The machining of titanium alloys classified as difficult machining materials. It is a major problem how to improve the machining efficiency of titanium alloys. 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 finite element method is the new method to study the machining process. The FEM and experimental method were used to simulate the cutting temperature of serrated chip while machining titanium alloy TC4. The simulated results were compared with the experimental results. The compared results indicated that the cutting temperature of serrated chip can be simulated by the simulation model well.
