Study on the Cutting Simulation and Experiment of Titanium Alloy

摘要

The finite element analysis software AdvantEdge is used to simulate the milling process of titanium alloy TB8 in two dimensions. Comparing with the experimental results, it can be concluded that simulation results are reasonable. Based on the model, the influences of the milling speed vc, the axial milling depth ap, the per-feed feed rate fz on the milling force are analyzed. The temperature field distribution at different milling speeds and the influence of milling speed on the rake face and relief face of temperature are studied. The results show that when milling titanium TB8, it is recommended to use higher milling speed, smaller axial milling depth and feed per tooth when conditions permit. The temperature distribution of the tool has a significant gradient change, the maximum temperature is located in the rake face of the main cutting edge near the tip of 0.01-0.02 mm position. Most of the cutting heat of Titanium alloy milling process is taken away, and only a small part of the heat is transferred to the tool and workpiece.
