    Abstract :

    Wire EDM is a non-traditional machining method primarily used for machining hard metals or those that would be impossible to machine with traditional techniques. The non-contact machining technique has been continuously evolving from a mere tool and dies making process to a micro-scale application. In this research paper, the machining of High Speed Steel (HSS) material using Wire Electric Discharge Machining (WEDM) with Brass as a wire electrode has been carried out. The pulse on time, pulse off time and servo voltage were selected as control process parameters of Wire EDM. Both Taguchi and Response Surface Method (RSM) techniques were applied to determine optimized process parameter to maximize Material Removal Rate (MRR) and minimize Surface Roughness (Ra). These techniques were compared based on time, trials and cost concern. The effect of process parameters on MRR and Ra was found by using Analysis of Variance (ANOVA).
