A Theoretical analysis on Electro Chemical Discharge Machining using Taguchi Method

Abstract

The Electrochemical discharge machining (ECDM) is a growing machining process that develops from the processes like electrochemical machining (ECM) and electric discharge machining (EDM), used in micro machining of usually non-conductive materials such as quartz, glass, composites and ceramics. In recently time the need of non-conductive materials has been grown rapidly in the field of aerospace, medical, electrical and optical applications. Such as these applications implicate machining with higher reliability and higher accuracy, ECDM process has lavish scope in this area. Some further methods also that can machine non-conductive materials but they have certain limitations. In the current time ECDM is an emerging process, continuously researchers are trying to improve and amend it as a better way for non-conducting materials. Currently this paper carried out a study on continuous improvements in ECDM in machining of glass in the ECDM, has been show their effect on material removal (MR). A Taguchi analysis on machining of borosilicate glass has also been obtained, wherein it is illustrated that increase in feed rate and electrolyte concentration increases the MR.
