ECM Process Characteristics

Abstract

This paper intends to deal with the process characteristics of ECM and how it is affected by the process parameters. This work shows a study of the intervening variables in electrochemical machining (ECM) of mild steel (C=0.08%, Mn=0.35%, P=0.014%, S=0.018%, Si=0.017%, Fe=rest). The material removal rate (MRR) was studied. Two parameters were changed during the experiments: feed rate and voltage. Sodium chloride solution was taken as electrolyte (100gm/lt). The results show that feed rate was the main parameter affecting the MRR.
