Finite element simulations of machinability parameters in turning of Inconel 718

Investigations of machinability characteristics by practical machining runs are inevitably tedious and costly routes. The aim of the current work is to model and simulate machinability characteristics in turning of Inconel 718. The DEFORM 3D finite element (FE) software was employed for this purpose. Machinability parameters like cutting force, cutting temperature, tool wear and chip formations are predicted under different cutting conditions. The predicted machinability parameters in this study are related with the experimental results found in the literature. A significant agreement has been observed between the obtained values through FE simulations and the values follow the trend when compared with results found in the literature. The FE simulations provide some direction to machinists to select the best possible cutting conditions for practical machining without conducting too many costly experimental runs.
