| Summary: | In obtaining the best quality of engineering components, the quality of machined
parts surface plays an important role. It improves the fatigue strength, wear resistance, and
corrosion of workpiece. This paper investigates the effects of wire electrical discharge
machining (WEDM) process parameters on surface roughness of stainless steel using distilled
water as dielectric fluid and brass wire as tool electrode. The parameters selected are voltage
open, wire speed, wire tension, voltage gap, and off time. Empirical model was developed for
the estimation of surface roughness. The analysis revealed that off time has a major influence
on surface roughness. The optimum machining parameters for minimum surface roughness
were found to be at a 10 V open voltage, 2.84 μs off time, 12 m/min wire speed, 6.3 N wire
tension, and 54.91 V voltage gap. |
