It is easier to numerically model the machining process assuming the orthogonal cutting conditions, however the realistic industrial machining arrangements are closer to the oblique machining conditions. In oblique machining the cutting edge is located at a certain inclination angle resulting in a third radial force component. The inclination angle in oblique machining arrangement has a controlling influence over the chip curling and resulting plastic deformation is more complex as compared to the orthogonal machining arrangements. The current study has incorporated a threedimensional finite element model to predict the machining of Inconel 718 using SIALON cutting tool materials under oblique machining conditions. The study incorporates different cutting edge-based inclination angles and resulting simulated machining performance has been reported. The machining performance has been evaluated by observing the simulated cutting forces, cutting temperature, and chip curling.
