Abstract: In this research work, the high magnetic field is applied on a single-point silicon aluminium oxynitride (SiAlON) ceramic cutting tool during the turning process of Inconel 718 (In718) to check its effect on surface roughness, tool temperature, and tool wear at different cutting speeds. A neodymium magnet is used to apply the magnetic field. The machining parameters selected for experimentations are speed - 5 levels, and magnetic field - 11 levels. In the experiment, Lorentz force is developed which helps for improvement of surface roughness. The experimental results showed that tool marks caused by the tool vibration are highly reduced, resulting in improvements in surface roughness. Moreover, because of the magnetic field fine particles are removed from the cutting zone resulting in decreased tool wear. Magnetic field affected on thermal conductivity of In718 which causes tool temperature is decreased but in the case without magnetic field machining temperature is increased as speed increases.

Keywords: Inconel 718; turning; magnetic field; surface roughness; tool wear.
