ABSTRACT: Research concerns the evaluation of the cutting insert condition on the microstructure of the surface layer after longitudinal turning of Inconel 718 alloy using carbide inserts. Value of the VBC wear index after dry machining with variable feed f and depth of cut ap was evaluated. White layer was observed up to 2,5 μm.
KEYWORDS: Inconel 718, white layer, inserts wear
STRESZCZENIE: Badano wpływ stanu ostrza na mikrostrukturę technologicznej warstwy wierzchniej po toczeniu wzdłużnym stopu Inconel 718 ostrzami węglikowymi. Oceniano wartość wskaźnika zużycia VBC po toczeniu na sucho ze zmiennymi parametrami posuwu f oraz głębokości skrawania ap. Zaobserwowano obecność białej warstwy na głębokości do 2,5 μm.
SŁOWA KLUCZOWE: Inconel 718, biała warstwa, zużycie ostrza
