Article dans une revue avec comité de lectureLAVISSE, BRUNO; ; BONDARENKO, Dmitry; ; GERMAIN, Guenael (Informa UK Limited, 2023-09-14)
The use of aluminum-lithium alloys in aeronautics is an efficient solution for lightweight structures, but its machinability can cause increased tool wear. The cutting temperature is one of the most important parameters ...

Article dans une revue avec comité de lectureKHOCHTALI, Haithem; AYED, Yessine; ; (Springer Science and Business Media LLC, 2021-04-08)
The machining of nickel-based superalloys is often challenging due to their excellent physical properties. High-temperature gradients are generated at the cutting zone, which accelerates the tool wear and impairs its ...
