The Electrochemical Discharge Machining (ECDM) process is a hybrid non-conventional machining process. It is used
for machinings hard and brittle materials such as borosilicate glass and ceramic materials. In the ECDM process, active
surface area ( dipped tool ) and peak current affect the discharge energy, which further influences the quality of the micro
holes. The present article is aimed to investigate the effect of active surface area and peak current on the performance
characteristics during the ECDM process. Experiments were conducted to investigate the affect of active surface area and
peak currenton Depth Of Penetration (DOP), the Hole Over Cut (HOC), and Material Removal Rate (MRR) based on the
reaction rate during ECDM of borosilicate glass. The experimental results reveal that both the MRR and HOC increase in
increasing the peak current and decreasing the active surface area. The maximum DOP and MRR were obtained at 5A peak
current with 2 mm tool immersion depth and 7A peak current with 1 mm tool immersion depth, respectively. The minimum
HOC was obtained at 2A peak current with a 3 mm tool immersion depth.
