Abstract

Wire electrical discharge machining (WEDM) is one of the efficient technologies of unconventional machining used to construct complex shape components, of hard materials or non-ferrous metals such as aluminum alloys. Qualitative assessment of wire electrical discharge machining (WEDM) of 2017T451 and 7075T651 aluminum alloys in terms of surface finish is studied. Three-factor and 3-level WEDM trials are operated by an L9 Taguchi’s orthogonal array to determine the influence of process parameters. Based on surface roughness (Ra) value, the signal-to-noise (S/N) ratio and analysis of variance (ANOVA) results reveal that the pulse on time (TON) and pulse off time (TOFF) are significant cutting parameters affecting the surface roughness (Ra). Surface topography of the treated materials shows that no cracks for the two aluminum alloys are considered in this work.
