Paper Title
A Comparison Study on Optimization of Process Parameters between Die sinking EDM and WEDM for Stainless Steel 304
  Nishant,  Dr. Soupayan Mitra

Die sinking Electro Discharge Machining (EDM) and Wire Electro Discharge Machining (WEDM) are two important non-conventional machining processes. In this present study the process parameters which normally influence the metal removal rate (MRR) and surface roughness (SR) are optimized both for EDM and WEDM and compared for machining AISI 304 stainless steel. AISI 304 steel has good wear and abrasion resistance and the machining operations are conducted with the Tungsten carbide electrode as tool. Here the machining experiments are done following Taguchi L9 design to analyze the effect of three important machining parameters viz., discharge current, pulse on time, and applied voltage on material removal rate and surface roughness. The signal-to-noise ratios associated with the observed values in the experiments are determined and Analysis of variance (ANOVA) is done to ascertain the factors by which the response parameters viz., Material Removal Rate and Surface Roughness are most affected both for EDM and WEDM. The respective influence contribution of each of the machining parameters on response varies are also maintained

Keywords- EDM, WEDM, Material removal rate, Surface roughness, Taguchi method
