Method of hole shrinkage radial forces measurement in Ti6 Al4V drilling
Communication avec acte
Résumé
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 thermome chanical loads applied to the workpiece and the tool. Nevertheless, the present study focuses only on the mechanical aspect and especially aims atshowing the development of an innovative method to measure the radial forces induced by the hole shrinkage phenomenon.
