3D FE- SIMULATION OF THERMALLY ASSISTED TURNING OF INCONEL-718 FOR CUTTING FORCES PREDICTION

This paper investigates the effect thermally assisted turning (TAT) of different cutting parameters (cutting speed, feed rate, and depth of cut) on cutting force under dry hard turning process of Inconel 718. 3D FE simulations based ABAQUS/explicit of both orthogonal and oblique turning processes were performed. the results indicated that 3D FE modeling provides the reliability to predict cutting forces during turning process by validation the obtained results with the experimental results. Also, the results indicated that 3D models of oblique machining have more accurate results as compare with orthogonal models although computing time is larger for 3D oblique machining models. In addition, the results show that the cutting force decreases significantly with increase cutting speed and workpiece temperature while it increases with increase the feed rate and depth of cut.
