Electrochemical Discharge Grinding
Electrochemical discharge grinding (ECDG) is a combination of electrochemical grinding (ECG) and electrical discharge grinding (EDG), with some modification of each. This article commences with a schematic illustration of a setup for ECDG using a solid bonded graphite wheel. It describes the process characteristics of ECDG in terms of current density, wheel speed, wear ratio, accuracy and finish, wheel maintenance, and profile grinding. The article concludes with a comparison of ECDG with EDG and ECG.
