Short summary
This work investigates the effect of electrode geometry on flushing capability and debris removal efficiency in Electrical Discharge Drilling process. Drilling operations on stainless steel 304 were performed using circular and side-cut electrodes. Experimental results were compared with respect to drilling performance as well as dimensional accuracy and surface quality of drilled holes. Three-phase three-dimensional CFD models were also developed to analyze the flow field at interelectrode gap.
