jms.5.3.13745 Technological Landscaping on Electro Chemical Discharge Machining of Non-Conducting Materials Abhishek Charak C.S. Jawalkar Journal on Material Science 2347–615X 5 3 31 37 10.26634/jms.5.3.13745 ECDM, ECM, Glass, Quartz, Ceramics, Material Removal Rate This paper discusses Electrochemical Discharge Machining (ECDM), which is a non-conventional process used in fabricating micro features, preferably on non-conducting materials. The role of mixed electrolyte in ECDM used by previous researchers along with its various concentrations have been discussed. The effect of process parameters like voltage and electrolyte concentration on Material Removal Rate (MRR) have been analysed along with its optimization; utilizing statistical tools like Analysis of Variance (ANOVA). Through the experimental results, it was observed that the MRR increased with an increase in electrolyte concentration up to a certain level and decreased with an increase in the stand-off distance. MRR increased with an increase in voltage up to certain stage of potential. The comparison is drawn between the effects of hollow and solid tools on MRR. The overall MRR is more for mixed electrolyte as compared to single electrolytes. The effect of tool size on MRR has also been discussed in the paper.
