This work is based on the analysis of vibrations generated during the classical shooting. The main objective is to improve the surveillance of the cutting device usury during its three phases of life. This analysis aims to demonstrate if there is a relation between the evolution of the usury and the measured length(vibrations)during the machining. To succeed , we have made many great campaigns by using tools in platelet and the monobloc in metallic carbureted engine. Thus, generated vibrations during the machining operations have been registered, following two axes on the machine tool thanks to the mono axial accelerometer situated on the turret. The first is oriented following the vertical direction x (radial), the second following z(axial) and parallel to cut effort. These directions have been qualified of privileged directions . however signals have been treated via two methods ; temporal method based on statistic indicators (RMS, kurtosis, skewness, variance, variance, average) and frequential method. Furthermore,, we’ll measure the electrical power and we have visualized and measured the width of the usury thanks to an optic microscope. Finally, the proposed methods in this work have permitted to determine the vibrating level of the signal and pertinent indicators permitting a surveillance of the tool usury of the classical turning cut.
Author Keywords: turning, cutting tool, usury tool surveillance, vibrating analysis, power cut analysis.

Abstract: (french)
Ce travail est basé sur l’analyse des vibrations générées pendant le tournage classique. L’objectif principal est d’améliorer la surveillance de l’usure de l’outil de coupe pendant ces trois phases de vie. Cette analyse vise à démontrer s’il y a une relation entre l’évolution de l’usure et les grandeurs mesurées (vibrations) pendant l’usinage. Pour y arriver nous avons effectué plusieurs campagnes de mesure en utilisant les outils en plaquette et le monobloc en carbure métallique. Ainsi les vibrations générées pendant les opérations d’usinage ont été enregistrées, suivant deux axes sur la machine-outil à l’aide de deux accéléromètres mono axial positionnés sur la tourelle. Le premier est orienté suivant la direction verticale X (radiale), le second suivant Z(axiale) et parallèle à l’effort de coupe. Ces directions ont été qualifiées de directions privilégiées. Cependant les signaux ont été traités via deux méthodes : la méthode temporelle basée sur les indicateurs statistiques (RMS, Kurtosis, skweness, variance, moyenne) et la méthode fréquentielle. Par ailleurs nous allons mesurer la puissance électrique et nous avons visualisé et mesuré la largeur de l’usure en dépouille à l’aide d’un microscope optique. Enfin les méthodes proposées dans ce travail ont permis de déterminer le niveau vibratoire du signal et des indicateurs pertinents permettant une surveillance de l’usure de l’outil de coupe en tournage classique.
