Abstract(s) :

(Anglais) 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. Wear tests have been conducted on a shaper using metalic cutters. The applied forces have been recorded continously while testing, and grooves have been laser-profiled afterwards in order to assess the cross sectional area of the cut at any time. The measurements have then been used to compute the cutting efficiency.
