Abstract
This study considers the effect of wire electro discharge machining (WEDM) parameter peak current (Ip) and pulse peak voltage (Vp) on the machined surface morphology of TiNiCu shape memory alloys. Various defects of machined surfaces were identified and correlated with parameter values and measured average surface roughness (Ra) and average surface depth (Rz). It was found that the nature of the machined surface is highly influenced by the nature of sparking, which is dictated by levels of peak current and peak voltage used during machining. Distinctions between machining parameters resulting in “rough-cut” and “trim-cut” machining are reported along with deviations in output responses, which counters the trend reported in the literature.
