Abstract
A versatile operational technique called Micro-Electrical Discharge Machining (Micro-EDM) is employed to initiate miniature holes in hard materials to enable efficient conduction in the applications of micro machining. Short-term discharge of electric pulses of a high discharge current between the tool used and the work piece eliminate material on the surface. A study was performed to evaluate the impact of Micro-EDM process characteristics on Stainless Steel 304 with the help of a brass electrode the high utility levels of the metal in several industries. The current study undertakes to experiment with pulse durations of 3 μs, 4 μs, and 5 μs at a current intensity range of 20A with an emphasis on performance measurements including Metal Removal Rate (MRR) and Tool Wear Rate (TWR).This is achieved by drilling 1.0 mm and 1.5 mm micro holes on SS 304. The Taguchi approach uses a mixed 2–3 design to assess the findings. Subsequently, the outcomes of the study of tiny holes related to both diameters are contrasted to determine the significance of factor variables.
