NOBRE, Joao PauloOUTEIRO, JoséRésumé
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.
