Modelling of material removal rate in electro discharge machining of nonconductive ZrO₂ Ceramic with kerosene and EDM oil dielectric fluid / Abdus Sabur … [et al.]

In this study electro discharge machining (EDM), a noncontact material removing process, is used for structuring nonconductive Zr02 ceramic. Adhesive copper foil is applied on the workpiece surface as assisting electrode to initiate the sparks. Experiments are conducted according to Taguchi approach...
