A first approach of tool-chip interface behaviour for high-speed machining modelling has been carried out by Al Brocail and 2010 and an empirical friction law has been first determined. This law has been established for high temperatures (initial sam

International audience; In numerical approaches for high speed machining, the rheological behavior of machined materials is usually described by a Johnson Cook law. However, studies have shown that dynamic recrystallization phenomena appear during ma
