An Investigation of Machining Time and Surface Roughness in Wire-EDM for Inconel 800

Article Preview

Abstract:

This paper presents an experimental investigation on the influences of EDM parameters on machining time and surface roughness for machining Inconel 800.Inconel800is widely used in construction of equipment that must have high strength and resist carburization, oxidation and other harmful effects of high temperature exposure. The selected WEDM parameters are pulsed current (210,220 and 230A), pulse-on time (2,3.25, 4.5, 5.75, 7 and 8.25μs) and pulse-off time (19 and 46μs). It has been observed that surface roughness increases with the increase of pulse-on time and pulse current. Similarly machining time decreases with the increase of pulse current and pulse-on time. Conversely, a decreased value of pulsed current and pulse-on time results in a better surface finish and increased machining time.
