Abstract
Electric Discharge Machining (EDM) is an electro-thermal non-traditional machining process having a widespread applications in automotive, aviation, miniaturized scale frameworks industries etc. EDM process is governed by thermoelectric vitality between anode (workpiece) and cathode (tool wire). EDM shoulders a fantastic part in the improvement of practical things with more dependable quality affirmation. Enhancing the material removal rate, surface finish and diminishing the tool wear rate and dimensional variation were paid exceptional attention in EDM. Generally copper, brass and graphite are utilized as tool (cathode) materials. In this experimental research work, SS 317 grade steel is machined in EDM by varying input factors and optimized the process using Full factorial method. Copper and brass electrodes were utilized as tool material on SS 317 steel which is oil hardened, non-shrinking steel. These steels are used for fine parts such as taps, hand reamers, milling cutters, engraving tools and intricate press tools which cannot be machined easily after hardening.
