It was shown that AEDG improves MMR and surface finish (SF) for both these materials as compared with EDM or electro-discharge grinding (EDG). The EDM was performed using the same graphite wheel as in the EDG without wheel rotation.

Owing to the contaminations in the small discharge gap of micro-electro-discharge machining (μEDM), generation of nonuniform nature of discharge pulses is more significant than in macro-EDM.To address the contribution in material removal of workpiece by each of these pulses, a pulse discriminating (PD) system which discriminates them into contributing and noncontributing types is generally used.
