ABSTRACT:
Electric Discharge Machining developed in 1940, 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 in the presence of a dielectric medium. All electrical conductive materials of any hardness and toughness are being machined by using thermal energy in EDM. Machining defects like clattering, mechanical stresses and vibration are eliminated becuase there is no contact between tool and workpiece. In the past few years, powder mixed Electric Discharge Machining is relatively new material removal process applied to improve the machining efficiency and surface finish.A suitable material (like Alumina, Sic, Graphite) in fine powder form is mixed into the dielectric fluid of EDM. Because of this, process is stable, improving machining rate (MR) and surface finish. The main objectives of research were design of experiments to perform experiments on PMD-EDM, analysis of response variables. Final Experiments were carried out to investigate the effect of powder mixed dielectric fluid in EDM by taking current, pulse on time duty cycle and different powder media (SiC, Al2O3, and graphite) as process parameter. Material removal rate (MRR) was taken as response variable during the electrical discharge machining of Inconel-718. The experiments were performed using Taguchi method. The effect of various input parameters on output responses were analyzed using analysis of variance (ANOVA).
