Examination of Surface Roughness Using Different Machining Parameter in EDM

(Department of mechanical engg FCET Ferozepur) ABSTRACT: Electrical discharge machining (EDM) is one of the important non-traditional machining processes and it is widely accepted as a standard machining process in the manufacture of forming tools to produce molds and dies. Since its introduction to manufacturing industry in late 1940s, EDM became a well-known machining method. The method is based on removing material from a work piece by means of a series of repeated electrical discharges, produced by electric pulse generators at short intervals, between an electrode (tool) and a part being machined in dielectric fluid medium.This paper describe the efeect of different materials on surface roughness produced. Paper helps in choosing right type of electrode material for specific purpose.
