Investigation of the machinability of non-conductive zro2 with different tool electrodes in EDM

Electrical discharge machining (EDM) is a non-conventional process where complex and difficult-to-cut materials can be machined. Adhesive copper foil as an assisting electrode (AE) is used to cover the zirconia (ZrO2) surface to start the primary spark between the tool electrode and workpiece. Keros...
