Micro-edm for micro-channel fabrication on nonconductive ZrO2 ceramic

In this study, microelectro-discharge (micro-ED) milling of nonconductive ZrO2ceramicsis investigated using a Cu tool electrode in kerosene dielectric. An adhesive Cu foil is firmly attached on the workpiece to initiate the sparks. After the machining of Cu foil, an electrically conductive carbonic...
