Orthogonal machining of Heat Treated Ti-10-2-3: FE and Experimental

Abstract

ABSTRACT Nowadays, finite element analysis is the best suitable approach to reduce the need for several experiments. This paper is based on the FE modeling and model validation via the experimental value of turning operation in 2D on heat-treated Titanium alloy (Ti-10-2-3 is also named as Ti-10 V-2Fe-3Al). Turning operation is treated as an orthogonal cutting process and this operation is simulated using Abaqus® explicit 6.14 software, with the help of Johnson–Cook material constructive model with boundary conditions. FE simulation results were validated with experimentally obtained forces and cutting temperatures during turning operation on different cutting thickness. Simulation and the experiment were conducted on the three different heat-treated conditions of the Ti-10-2-3 like Solution Treatment and Aging (STA), Annealed and Solution Treated and Overaged (STOA). The model validation showed that the average errors in the prediction and the experimental values are cutting force 4%, feed force 3% and temperature 11%. In this model, the simulated value of the average feed force was slightly less than the experimental value due to the consideration of actual friction between tool–chip interfaces on the rake face.
