N2 - This study investigates the machinability of nonconductive Aluminium nitride (AlN) ceramics using die sinking Electro-Discharge Machining (EDM) machine. A three layers coating consisting of silver by Physical-Vapour Deposition (PVD), carbon layer and silver nano-powder were deposited on the ceramics materials to aid in conducting the EDM operation due to the conductive properties of the coating. Scanning electron microscope and optical microscope were used to characterise the machining parameter. The effects of the process parameters such as peak current, pulse on time, and duty cycle were studied on the overcut of the hole generated on the surface. It was found that, with the increase of peak current value, the overcut value increases, whereas, with the increase of pulse off time the overcut decreases.
