Abstract

Electrochemical Discharge Milling (ECD milling) process encounters some problems like the uneven edge of the machined channel, lower machining depth, uncontrollable spark discharge, etc. The primary cause of those issues is a lack of gas bubbles in the machining area, which are necessary for good spark discharges. Due to the buoyancy of the liquid, gas bubbles cannot remain at the tool-electrode tip and poor flushing arises from feeding the tool-electrode on the top surface of the workpiece. In this study, horizontal tool-electrode and vertically upward feeding technique has been introduced to solve the problems that arise during the existing feeding technique. The material removal rate (MRR) and overcut during ECD milling are observed and analysed by changing the applied voltage, concentration of electrolyte and feed rate of tool. MRR and overcut are found as 5.025µg/min and 116.86µm respectively at 40V, 20wt% concentration of electrolyte and 50µm/sec of feed rate.
