An Ecdm Approach for the Development of 3d Microchannels on Glass Substrates

Microchannels proved to be most favorable component for microfluidic applications.Electrochemical discharge machining provides cost effective solution to produce micro profiles on nonconductive and conductive materials regardless of their hardness, brittleness and surface reflectivity.The present study discusses the effect of applied voltage, electrolyte concentration and workpiece feed rate during fabrication of microchannels on glass substrates.The output parameters studied were material removal rate and microchannel width over cut.The optimum combination of applied voltage (= 50V), electrolyte concentration (= 20%) and feed rate (=16mm/min.)yields the best accuracy of the micro channels.
