Finite element modeling in drilling of Nimonic C-263 alloy using deform-3D

Abstract

The paper proposes a simulated 3D Finite Element Model (FEM) for drilling of Nickel based super alloy known as Nimonic C-263. The Lagrangian finite element model-based simulations were performed to determine the thrust force, temperature generation, effective stress, and effective strain. The simulations were performed according to the L27 orthogonal array. A perfect plastic work piece was assumed, and the shape is considered to be cylindrical. The spindle speed, feed rate, and point angle were considered as the input parameters. The work piece was modeled by Johnson-Cook (JC) material model and tungsten carbide (WC) was chosen as the drill bit and the body was assumed to be rigid. The demonstrative results of the thrust force and the temperature at drill bit cutting edge were substantiated with the simulated results and a percentage error was observed within 10%. Further, simulated results of effective stress and strain were also observed.
