Abstract

Electrical Discharge Machining (EDM) is one of the most successful and widely accepted processes for production of complicated shaped and tiny apertures with high accuracy. The objective of this paper is to illustrate the influence of various parameters of EDM on the machining characteristics. The effectiveness of EDM process has been evaluated in terms of the Material Removal Rate (MRR), Electrode Wear Rate (EWR), and the Surface Roughness (SR) of the work piece produced. High MRR, low EWR and high SR of the work piece are conflicting goals, which cannot be achieved simultaneously with a particular combination of control settings. Various parameters have to be controlled separately generally one at time, to study their influence on response variables. In the present study, the influence of current intensities on the MRR, EWR, and SR has been investigated for different electrode materials (Aluminum, Copper, and Graphite).
