Finite Element Analysis on Single Abrasive Grinding Ti6Al4V Alloy

Abstract

The paper presents the simulated 3D Finite Element Model (FEM) while grinding the Ti6Al4V alloy using a single abrasive wheel. Grinding simulation was carried out using a Lagrangian finite element based machining model to predict the tangential cutting force, temperature distribution at grinding zone and the effective stress and strain. All simulations were performed according to the cutting conditions designed, using the plane up-grinding. The work piece was considered as typical materials to machine difficulty. As the cutting speed is increased from 15 m/min to 33 m/min at higher feed rate, a maximum value of 750 MPa stress and higher temperature localization to an extent of 900°C at grinding zone were observed.

Grinding temperature and its consequences on induced residual stresses during grinding of nickel-based superalloys: a review

“…In the case of aerospace materials, the due to the generation of high heat in the grinding zone also affects the subsurface of the machined surface, which is more unfavourable and of greater concern, apart from tool wear [26][27][28]. Therefore, the prediction and control of grinding temperature during grinding of tough-to-machine materials are of great concern [29][30][31]. Sharma et al [32] proposed a three-dimensional model to find out the temperature variation using finite element analysis during grinding of nickel-based superalloy Inconel 718.…”
