“…The study showed that the EDM of nonconductive or partially conductive materials is feasible due to the formation of a conductive layer over the work surface . This conductive layer helps in continuing the spark generation as the tool electrode moves past the AE.…”

“…For Al 2 O 3 machining by EDM is more critical because the creation of the conductive layer depends upon the degree of purity of the material [20]. Mohri et al report that due to the higher free forming energy of Al 4 C 3 compared to those of ZrC and TiC the generation of a conductive layer is more difficult on Al 2 O 3 which leads to a more unstable process [13,26].…”

“…Another possibility is the usage of conductive silver lacquer [16,27] which can be printed and sintered or applied by brush. Mohri et al also used a method called "baked-carbon" to realise a starting layer [13,26]. The most important requirement is the mechanical attachment of the conductive layer onto the workpiece surface.…”

“…It is also observed that surface roughness increases with the increase of discharge current [2,8]. However, EDM of Al2O3 is found to be more difficult to machine because of the unsteady formation of electrically conductive layers on workpiece surface during the machining process [5,13]. Under this circumstance, attaining the optimum machining outputs such as a higher MRR and lower SR is complicated [14].…”
