A Comprehensive Review on Modeling and Simulation Studies in Electro-Chemical Discharge Machining

Abstract

Glass has wide application in the production of micro components. Electro-chemical discharge machining (ECDM) has proven an inexpensive and potential micromachining method for such nonconductive materials. ECDM has the electro-chemical machining (ECM) and electric discharge machining (EDM) constituent processes. It overcomes limitations and provides benefits of both constituent processes, namely EDM and ECM. The major limitation in the industrial application of this technique is controlling of gas film formation and discharge activity. Researchers have attempted numerous studies, both experimental and simulation, exploring the physics behind the process. In view of appraising research carried out in recent years, the present work reports a comprehensive review of modeling and simulation studies in electro-chemical discharge machining along with a brief introduction to ECDM. Different modeling and simulation approaches applied by researchers were discussed. The importance of various simulation parameters and material removal criteria were justified.
