Corner accuracy occurring in wire electrical discharge machining (WEDM) is influenced by parameters such as vibration, lag, and excessive discharge, etc. This study proposed an optimization method which can improve the corner of WEDM process. The pulse-on time (ON), pulse-off (OFF), open circuit voltage (OV), servo (SV), tension (WT), flushing pressure (WA) were selected to investigate influenc...

Abstract. In this paper, helium-assisted near-dry wire-cut electrical discharge machining (NDWEDM) method molybdenum wire has been used to reduce the environmental impact and cut M2-HSS material. The pressurized non-reacting helium gas mixed with a small amount of water (Helium-mist) is as dielectric fluid accomplish adequate cooling flush-out debris. new experimental setup developed conduct WE...

Advanced Ceramics find wide range of industrial applications. Cutting of advanced ceramic (SiC) is very difficult using conventional machining methods due to its low fracture toughness. In the past few years, researchers have claimed successful machining of ceramic composites using EDM process. Furthermore, increasing trend, necessity of miniaturization, micro components in MEMS and semiconduct...
