Electric Discharge Machining is a non-traditional machining process, used for machining of hard and tough materials, which are difficult to machine by traditional machining processes. The greatest difficulty of EDM is low material removal rate, high tool wear rate, surface roughness, end wear and corner wear. In this research work, an experimental investigation was performed to determine the mechanical properties of Angstrofine Graphite using negative polarization. The work presented in this paper is the effects of current decrease, pulse time (tone), and duty cycle on output parameters such as Material Removal Rate (MRR) and Surface Roughness(SR)
