The adequate selection of manufacturing conditions is one of the most important aspects to take into
consideration in the die-sinking Electrical Discharge Machining (EDM) of conductive martial, as these
conditions are the ones that are to determine such important characteristics as: surface roughness, Electrode
Wear Ratio (EWR) and Material Removal Rate(MRR), among others. In this research, the influence of different
EDM parameters (current, pulse on-time, pulse off-time, arc voltage) on the surface quality ,material removal
rate and electrode wear ratio as a result of application copper electrode to cold work steel DIN1.2379 has been
investigated. Design of the experiments was chosen full factorial in finishing stage. Finally, the artificial neural
network has been employed to predict the surface quality, material removal rate and electrode wear ratio. The
experiment results indicated a good performance of proposed method in optimization of such a complex and
non-linear problems.
Key words: Artificial Neural Network (Ann), Electrical Discharge Machining (EDM), electrode wear ratio, material removal rate, surface quality, ,
