Wire Electro Discharge Machining (WEDM) process plays a significant role to cut complex and intricate shapes of components in all conductive materials. In order to improve the machining economics and the product accuracy of wed med parts a suitable modeling is essential. In this direction, several researchers have attempted previously. In this present analysis to predict the performance characteristics namely the Material Removal Rate (MRR) and surface roughness a general purpose statistical software, MINITAB was applied. Stainless Steel (ss410) material was selected as work material to conduct experiments. A 0.25 mm diameter Brass wire was applied as tool electrode to cut the material. Experiments were planned as per Taguchi’s orthogonal array. Each experiment has been performed under different cutting conditions of pulse on time, off-time, wire speed, wire tension, dielectric pressure and current. In each experiment the performance characteristics such as material removal rate and surface roughness were carefully measured.

Keywords : INDEX TERMS:- Material Removal rate, Surface roughness, Brass wire, WEDM, Taguchi’s Orthogonal Array (OA).
