Abstract |
|
Inconel 718 super alloy is one of the difficult to machining material employed widely in aerospace industries. The main objective of this study its implements a reliable finite element model for orthogonal machining of Inconel 718 alloy and prediction of the microstructure changes during the process. The experimental results of surface roughness and material removal rate were taken in to account to identify the most suitable cutting parameter among the number of trials. The finite element numerical model was calibrated using an iterative procedures Newton Rapshon method. The results shows that a very good agreement has been found between the machinability analysis both in experimental and simulation. The FEM analysis has predicted some useful response using Deform 3-D. |
