Implanté sur deux sites, le campus d’Angers et le pôle de réalité virtuelle de Laval, le LAMPA intervient dans les domaines de l’innovation, des procédés avancés de fabrication et de durabilité des matériaux et des structures. Le numérique et le virtuel sont au cœur des travaux de recherche, par exemple la simulation numérique du procédé pour la compréhension des phénomènes thermiques et mécaniques en jeu.

  Identification of friction coefficient between uncoated carbide tool and Ti-6Al-4V alloy under different lubrication conditions 

  Communication avec acte

  FERSI, Achraf; YESSINE, AYED; BRUNO, LAVISSE; GERMAIN, Guenael (Materials Research Forum LLC, 2024-05-15)

  During machining, the friction between the tool and the workpiece (cutting face and flank face) is a significant tribological phenomenon because it strongly influences the cutting operation. Indeed, higher friction leads ...
