Experimental Investigation into Electrical Discharge

INTRODUCTION.Electrical discharge machining is a thermo-electrical material removal process,in which tool electrode shape is reproduced mirror wise into a work material (Beri et al.,2008).The mechanism for removing material primarily turns electrical energy into thermal energy through a series of successive sparks between the electrode and the work-piece in a dielectric fluid.Electrical Discharge Machining ( EDM ) Design With the RC,LC,or RLC type power system,the discharge energy comes from a capacitor that is connected in parallel with the machining gap.As a result of the low impedance of plasma channel,the discharge duration is very short (less than 5 msec),and the discharge current isEXPERIMENTAL AND INVESTIGATION OF MICROKeywords Micro-EDM,machining,micro hole,AISI 1040,anova,taguchi method.INTRODUCTION Electrical discharge machining (EDM) is a non-traditional concept of machining which has been widely used to produce dies and molds.It is also used for nishing parts for aerospace and automotive industry and surgical components [1].This technique has
