The current study focuses on the drilling of meso-holes in EN_31 steel using electrical discharge drilling (EDD). Experimental analyses were conducted using an EDD machine, with process parameters including depth of hole, current, T_ON (on-time), and T_OFF (off-time). To optimize machining characteristics, a Taguchi L-27 orthogonal array design of experiment was employed. The main response variables studied were material removal rate & Tool wear rate with the use of a 0.8mm diameter brass & Copper tubular electrode. Additionally, microstructure analysis was conducted using microscopic instruments to examine the results in detail.
