文摘

Unconventional machining processes are used only when no other traditional machining process can meet the necessary requirements efficiently and economically. Determinations of machining parameters are essential for the effective utilization of these processes. Electric Discharge Machining (EDM) is a thermo-electric non-traditional machining process in which material removal takes place through the process of controlled spark generation between a pair of electrodes which are submerged in a dielectric medium. This paper describes the selection of machining parameters Discharge Current, Pulse ON Time and Pulse OFF Time in EDM for the machining of AISI202 stainless steel material. The use of grey relational analysis for optimizing the machining parameters Material Removal Rate (MRR) and Surface Roughness (SR) is introduced. Grey relational analysis is applied to find the Grey Grade and it is used to represent the multi-objective model. The experimental work in this research to know effect the machining parameters on EDM and conclusion mis effect on the Metal Removal Rate (MRR) and Surface Roughness (SR). Grey relational grade is used to find the optimal parameters.
