In this paper investigation of micro-channels fabrication using electrode sheets in die-sinking electrical discharge machining (EDM) process has been done. The micro-channels were fabricated on AISI D3 die steel using sheets of copper as electrode material. Parametric optimization for process parameters of EDM has been done using Taguchi Method. The control parameters taken were current, pulse-on time, pulse-off time, and voltage. Surface roughness was taken as response parameter.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
