Characterising energy efficiency of Electrical Discharge Machining (EDM) processes

Abstract

Energy efficiency in manufacturing has become a critical topic among researchers and industries. As a result, there has been a worldwide effort to improve the transparency of the energy efficiency for all manufacturing activities. The studies of unit processes have provided fundamental knowledge for characterising energy efficiency of manufacturing processes, which has been initially applied to conventional processes (e.g. turning, milling, injection moulding, etc.). However, studies in nonconventional manufacturing processes remain absent. This paper presented an empirical approach to characterise the energy efficiency of electrical discharge machining (EDM) processes. The derived model rev..
