Abstract:Modern trend towards miniaturization has given a new impetus to the development of nontraditional small hole drilling techniques. Electro jet drilling (EJD) is one such promising technique which is finding ever increasing applications in several industries including aerospace, space, medical, automobile and microfabrication (electronic and computers). The present study investigates the relationships and parametric interactions between three controllable variables on the material removal, radial overcut and hole taper in the EJD process. Experiments have been conducted on SUPERNI 263A workpieces. Applied voltage, electrolyte concentration and feed rate were selected as independent process variables. The responses have been modelled using a response surface model based on a central composite rotatable experimental design. The significant coefficients were obtained by performing analysis of variance (ANOVA) at 1% and 5% level of significance. It was found that applied voltage, electrolyte concentration and feed rate have significant effect on the material removal, radial overcut and hole taper.
