Analysis of Roundness Error and Surface Roughness in the Electro Jet Drilling Process

摘要: ABSTRACT A modern trend towards miniaturization has given a new impetus to the development of nontraditional small hole drilling techniques. Electro jet (EJD) is one such promising technique, and finding ever-increasing applications in several industries including aerospace, space, medical, automobile, microfabrication (electronics computers). This paper reports experimental findings on effects important process parameters as applied voltage, capillary outside diameter, feed rate, electrolyte concentration, inlet pressure quality holes (<800 μm dia) produced by using EJD process. Roundness error surface roughness have been used response for evaluating holes. The experiments were performed SUPERNI 263A material. An analysis variance (ANOVA) test significance variables at 5% level indicates that voltage concentration significantly affect respo...
