The purpose of this article is to compare time based maintenance (TBM) with condition based maintenance (CBM) relative to cutting tools in the process for removing material. We describe the fault detection (FD), method based on the use of the analytical model of the roughness of the work pieces to be machined. This model is established under given cutting conditions and calculated according to the maximum desired roughness. Experimental results are presented for the cutting tool TBM on the one hand, and for the validation of the FD method allowing CBM on the other hand.
