A Review of the Effects of Process Parameters on Machining and Surface Quality in Wire EDM of Inconel Alloys

Inconel-based superalloys are famous for their exceptional high-temperature resistance and ability to maintain robust strength at high temperatures. Because of their superior hardness and higher tool wear rate, traditional machining processes provide significant challenges when dealing with these extreme temperatures superalloys. To address these challenges, modern manufacturing technology called Wire Electrical Discharge Machining (WEDM) is applied. WEDM, an advanced thermal machining process, is effective at accurately cutting components with changing hardness and complex shapes. This article reviews machining Inconel alloys in high-temperature applications, with an emphasis on machining performance, surface quality, and a literature overview. Furthermore, it highlights the current research landscape in WEDM, emphasizing the demand for additional research contributions in the context of Inconel alloys for future advancements in the field.
