To optimize machining processes in Electrical Dischange Machining (EDM) on a certain machining area, it is required to control its machining parameters such as electrical current (I) and pulse on time (Ton). This research aims to study the effect of machining parameters on electrode wear (EW) and metal removal rate (MMR) in EDM processes. It also attempts to investigate the taper effect in a hole machining by using EDM. To study the influence of machining area, several electrode diameters are employed, i.e. 10 mm, 12mm and 20 mm. Experiment is performade on AISI 1045 steel by using copper electrode. The result shows that Ton and I influences EW and MRR ia an opposite way. It also reveals that larger diameter electrode tends to decrease the ratio of EW and MRR. To obtain an optimum machining with smaller taper efect, it is recommended to use Ton, between 700 sec. With those Ton values, the optimum condition is given by I value of 6 Amp.
