The work presented in this thesis is a part of European project ACCENT and fits into the context of using process monitoring in the manufacture of critical parts for aircraft engines. The aim is to define a monitoring technique for the tool wear in the machining of the central bore of a high pressure disk made in nickel based superalloy. The major stages can be identified in our approach: identification of tool failure modes in drilling Udimet® 720 LI, defining the relationships between wear and measured physical quantities and finally, a proposal for monitoring strategies based on the previous results. In order to complete the objectives, an experimental protocol was defined. The experimental campaigns allowed us to characterize the drill ...
