Study on Simulation and Experiment of Drilling for Titanium Alloys

Abstract:

To investigate the drilling process of titanium alloys, the three dimensional finite element model of two flutes twist drill was established. The drilling process of Ti6Al4V was simulated based on the presented model. In addition, the drilling experiments were carried out under the different spindle speed and feeding speed. The drilling forces of the experiment and simulation were achieved. The result of simulation agrees with the result of experiment well. It proves that the finite element model is correct. Simultaneously, the results show that more high drilling speed can improve the quality of hole in drilling process of Ti6Al4V obviously.
