3D Finite Element Analysis of Drilling of Ti-6Al-4V Alloy

Drilling is an important machining process. A 3D FE model of drilling titanium alloys is developed using commercial finite element software DEFORM 3D. Simulations are carried out under different feed rates and drilling speeds to investigate the effect of drilling parameters on machining performance. The simulation results indicate the influence of machining parameters on drilling force, torque, and maximum tool temperature. The optimum drilling parameters are also recommended for drilling of Ti-6Al-4V according to the FE simulations. Keywords-drilling; ; ;
