Wire electrical discharge machining (WEDM) is an important technology, which demands high-speed cutting and high-precision machining to realize productivity and improved accuracy for automotive, manufacturing of press stamping dies, prototype parts etc. In this present work, investigations of cutting performance with pulse on time, pulse off time, servo voltage, wire feed, current and cutting speed were experimentally investigated in wire electric discharge machining (WEDM) process.

The cutting performance outputs considered in this study are material removal rate (MRR) and surface roughness. Experimentation has been completed by using Taguchi's L16 orthogonal array under different conditions of parameters. The aim of the present investigation is to develop the selection of an optimal combination of WEDM parameters for proper machining of SS 304 to achieve better surface roughness and Materials Removal Rate (MRR).
