Force and Thermal Variational Analysis by FE Approach on Dry Turning of Inconel 718
In the present work, dry turning process of Inconel 718 was simulated using DEFORM software. The Johnson–Cook fracture model was implemented in the FEM platform to develop and to analyse the 2D turning process model. The existing dire needs to reduce environmental pollution, and production costs have forced the manufacturers to limit the use of cutting fluids. In view of the above, the process was simulated at dry machining condition to investigate the influence of the two critical input factors: cutting speed (at 125, 300 and 475 m/min) and feed rate (at 0.05, 0.10 and 0.15 mm/rev). The variational analysis of the predicted machining responses, viz. cutting force, feed force, workpiece and tool interfacial temperature showed an incremental trend with time and cutting speed, respectively. The temperature simulation results were in agreeable concordance with the experimental results, from existing literature, with a maximum error of only 3.38%.
