Electrochemical Discharge Machining for Micro-Channel Cutting on Electrically Non-Conducting Material

Abstract

The present research work is based on the detailed experimental observations on the performance characteristics of ECDM set-up during channel cutting operation. The electrochemical discharge machining (ECDM) process have been applied successfully for micro-channel cutting on electrically non-conducting material like glass irrespective of its chemical and mechanical properties and also the tool geometry. It has been found that the MRR and Width are increase with the increase of applied voltage at fixed electrolyte concentration. Also it is observed that the MRR and Width varies with respective to the nature of the tool. The least WOC is observed at applied voltage of 50 V with 15 wt% concentration of NaOH salt solution using curved tool.
