Abstract

In this paper, an analytical approach is proposed to model chip formation in the case ofturning process. Numerical simulations of chip genesis are performed in order to fitefficiently the proposed analy- tical model. In particular, cutting edge radius influence,temperature and internal stresses distribution are studied using finite element modelling.Numerical model setting is made with experimental and literature data using forces andchip thickness.
