Numerical Modelling of the Thermal Effects on Material in Drilling Processes Ti6Al4V Alloy

It has been developed a bidimensional finite element model, which considers the thermal analysis of the material during the dry drilling of Ti6Al4V. Thermal loads that affect material have been calculated based on three-dimensional numerical models and the evolution of the torque experimentally measured in dry drilling of Ti6Al4V. Results of the numerical model have been compared with temperature values reached in the material at 1 mm from drill wall that was obtained experimentally. The developed numerical model to determine the evolution of the temperature in the material obtained during the drilling process gives relevant information for the control of thermal damage due to machining.
