Abstract
The need for electrochemical discharge machining (ECDM) has risen recently owning to the desire to produce micro-features in hard-to-machine materials. Electrolytes and their feeding methods play vital role that determine the machined surface characteristics. Sodium hydroxide is generally most preferable electrolyte media for ECDM but hazardous in nature. Hence, there is need to investigate the other alternatives that can be sustainable, environmental and user friendly and can improves the overall efficiency, repeatability and accuracy of ECDM process. This paper overview the research work conducted in the subject of different electrolytes and the parameters that affects the electrolyte performance. In the current paper, the electrolytes have been classified into four major categories namely alkaline, neutral, acid and hybrid electrolytes. This work includes a comprehensive overview of process mechanism and capabilities of different electrolytes regarding work material and machined features. The effect and classification of electrolyte feeding methods have also been included. Moreover, this paper discusses the possible future opportunities that can be explored to improve machining characteristics of ECDM.
