Simulation of Inconel 718 alloy machining with respect to the modified material model *

STRESZCZENIE: W artykule przedstawiono badania symulacyjne obróbki części lotniczej. Model symulacyjny skrawania stopu Inconel 718, zbudowany w oparciu o sformułowania Lagrange’a, zawiera model materiałowy Johnsona-Cooka. Zaprezentowano zależność wyników obliczeń symulacyjnych od charakterystyk modelu materiałowego, opisujących odkształcenie plastyczne, prędkość odkształcenia i temperaturę.

SŁOWA KLUCZOWE: symulacja obróbki, Inconel 718, model materiałowy

ABSTRACT: The paper presents simulation researches of the aeroplane part machining. A simulation model of Inconel 718 alloy machining based on the Lagrangian formulation contains the Johnson-Cook material model. The dependence of simulation results from the material model formulations (plastic strain, strain rate and temperature) was presented.

KEYWORDS: simulation of machining, Inconel 718, material model
