[en] Ongoing research at the Faculte Polytechnique de Mons focuses on determining the processes and parameters which control the cutting response of worn cutters. In particular, this paper presents a new approach under development for understanding wear mechanisms by continuously analysing the evolution of wear in term of cutting efficiency. Cutting efficiency can be computed at any time during a wear test by measuring both the forces applied on the tool and the cross sectional area of the groove being cut.
