Stainless steel is a material which has high corrosive resistance and oxidation at temperature with the combination of chromium, nickel, niobium as primary constituent. This difficult to machine complex shape taken by using wire cut electric discharge machining. Wire electrical machining nontraditional process widely for cutting shapes. review paper involves EDM optimization parameters. Pulse i...

In micro-electrical discharge machining (micro-EDM), dielectric plays a significant role during the machining process as different types of dielectrics have different chemical compositions, cooling rates and dielectric strengths. For this, dissimilar process responses are accounted when machining in EDM at micron level. The present paper investigates micro-EDM characteristics such as material r...
