| Résumé | An experimental-numerical methodology is applied to evaluate the residual stresses induced by drilling of Ti-6Al-4V alloy. The influence of ultra-high cutting speeds on the residual stress distribution is analysed. These ultra-high cutting speeds are produced by a turbine system powered by compressed air, which are commonly used in the hole-drilling equipment for residual stress measurements. The applied hybrid methodology has demonstrated an important role on the optimization of the drilling operations parameters for an improved residual stress distribution. (C) 2015 The Authors.
