Experimental Investigation of MRR and DOC and Comparison of Pressurized Electrolytes in Micro-Hole Drilling through ECDM Process
Among the existing non-conventional machining methods, electrochemical machining (ECM), electrochemical discharge machining (EDM), and wire- EDM are the most convenient for nonconductive materials like glass and ceramics . Irrespective of their merits there are many associated problems which need to be solved before utilizing these processes for machining glass. The most important problem encountered are low material removal rate (MRR) and high diameter of overcut. (DOC)
A new method called pressurized flow ECDM (electrochemical discharge machining) is used on sodalime glass with the help of mixed electrolytes NaNO3 + NaOH and NaCl+NaOH to check observing parameters MRR and DOC. On comparing with the observing parameters of both electrolytes, MRR and DOC were recorded 2.160 g/min and 1.2213 mm, which are respectively better compared to conventional ECDM.
