摘要：

This work deals with the phenomenon of hole shrinkage during Ti6Al4V drilling. Indeed, the shape and dimensions of the drilled hole, as well as the heat generated by the operation depend on this phenomenon which is caused by multiple factors, including the relaxation of internal residual stresses, thermal expansion and diverse thermomechanical loads applied to the workpiece and the tool. Nevertheless, the present study focuses only on the mechanical aspect and especially aims at showing the development of an innovative method to measure the radial forces induced by the hole shrinkage phenomenon.
