Cu–Al–Mn ternary shape memory alloys (SMAs) were synthesized and investigated for their surface roughness (Ra). Cu–Al–Mn SMAs were prepared through the ingot metallurgy method with aluminium (Al) content of 10–15 wt.% and manganese (Mn) content of 0-10wt.% and the rest is copper. After the heat treatment process, the alloy which exhibited an excellent shape memory effect was subjected to machinability studies in Wire EDM (Electrical Discharge Machining). In the context of Wire EDM, experiments were carried out using Taguchi's L9 orthogonal array (OA). Taguchi's method was used to obtain the optimum value of surface roughness. The effects of pulse duration, pulse interval, and peak current on surface roughness were studied using a technique that combined orthogonal array (OA) and analysis of variance (ANOVA). The obtained results revealed that peak current is the most significant factor affecting the Ra. From the Taguchi method, the best machining parameters combination settings are pulse duration (100 µs), pulse interval (32 µs), and peak current (1A) to meet the optimum value of surface roughness. The main purpose of the present investigation is to check for its machinability by identifying the machining performance, material behaviour and finally to optimise wire EDM machining parameters for Cu–Al–Mn SMAs using Taguchi’s optimization technique.
