Abstract(s) :

(Anglais) Cutting tools replacement is an important industrial concern because of the costs that stem from them. In many cases, cutting inserts are replaced either too late or too early. Consequently, either workpieces are scraped or cutting inserts are wasted. That is why there is a need for on-line evaluation of cutting tool wear, hence their residual lifetime before replacement. This estimate may be achieved through condition monitoring, either using direct measurements on the tool, or indirect measurement through machining variables or production quality. The condition monitoring data may in turn be used in statistical or probabilistic models, which are built with help of experimental data or information from numerical models. In the case of this work, the Cox Proportional Hazards Model is used with additional information from numerical models and cutting forces monitoring.
