Effect of Carbon Nano Tube Addition with Dielectric Fluid in Die Sink EDM

Abstract

Advance machining processes such as Electrical Discharge Machining (EDM) have been extensively discussed these days due to its novel applications in industry. Series of experiments are conducted across various researchers for performance improvement of the EDM process. Mixing micro/nano powder in working fluid for better result of material removal rate is one of the developments in conventional EDM process, known as Powder Mixed EDM. Many Researchers got successes in getting mirror like surface finish in PMEDM at low energy level, but still there will be improvements are possible by using Nano powders. Due to excellent performance in dielectric and better physical properties of the Carbon Nano Tubes (CNT’s), there is need of generalization of CNT based Powder Mixed Electric Discharge Machining (CNT-PMEDM) to increase industrial application. But less work has been reported in NPMEDM, this paper aim is to discuss all CNT’s based experimental investigation in Die Sink EDM process and its future scope to help the researchers for further development in it. In this paper details about Carbon Nano Tube and its applications as additives in EDM process to get better results are presented which helps for finding research gap and future scope in CNT-PMEDM process.
