Abstract
EDM is a non-contact machining process widely used for shaping electro-conductive materials regardless of their hardness. In EDM material removal takes place by a series of recurring electrical sparks between the tool electrode and workpiece. In this study the effect of variation of discharge current on various machining parameters including Metal removal rate (MRR), Tool removal rate (TRR) and Surface roughness has been considered. A total of 32 experiments were conducted on four different workpieces i.e. Die Steel-D3, En-8, En-19 and Stainless steel (SS-AISI-440C) with the help of Copper and Aluminium electrodes. In this study Die-Sinking EDM has been employed and the results are shown with the help of graphs.
