Abstract: Inconel-625 is a nickel-alloy based material with superior properties such as high fatigue strength, high hardness, and oxidation resistance. These properties make it suitable for applications in marine, aerospace, and power generation industries. Due to its high hardness, the material is difficult to machine by conventional machining methods such as turning, milling or grinding. For this reason, an alternative method known as Wire Electrical Discharge Machining (WEDM) can be adopted for such materials. In this paper, WEDM is optimized through Taguchi optimization technique. Inconel-625 plates of 10 mm thickness were used as specimen in experimental work. For maximum material removal rate (MRR) and minimum surface roughness (SR), it was observed that the optimum pulse- on time (TON), wire feed rate (WF), and gap voltage (SV) could be set to 0.4 us, 10 mm/min and 68 V respectively.
