Estimation of Thermal Effects in Dry Drilling of Ti6Al4V

This work focuses on the dry drilling of titanium alloy Ti6Al4V. The main objective is establishing a methodology to quantify the heat generated in the material, and the heat fluxes towards it during a machining process. For the thermal effects determination in the machined material, a tridimensional finite element model of drilling was developed. The numerical model was validated experimentally. From the thermal distributions obtained numerically, the heat that acts on the material due to the action of the edges of the tool it is determined.
