Etude numérique et expérimentale du formage incrémental pour les pièces de petites dimensions

Incremental Sheet Forming processes have been demonstrated in recent studies as a very promising technology to manufacture sheet metal parts by the CNC controlled movement of a simple generative tool. In glance with its various advantages, such process has been introduced as an alternative to reduce costs resulting from stamping technology when small batches or prototypes have to be manufactured. In this paper, an application is carried out accounting flexibility of the process linked to the fact that the punches or dies are avoided. Although the process still needs a further optimization, preliminary results have been obtained through experimental tests to manufacture micro parts. At the same time, a FEM analysis has been carried out in order to get the characteristics of the formed parts. Mots-clefs : Formage Incremental ; etude numerique et experimentale ; microcomposants
