Shape memory alloy (SMA) titanium with a nickel base is becoming more and more desirable for usage in various applications. These SMAs provide several difficulties during ordinary machining. In the ongoing research, the wire-electric discharge procedure has recently been attempted to be used to manufacture the super-elastic nickel-titanium (Ni_54.1Ti_45.9) material. The good performance of NiTi in medical and other applications depends on effective and net-shape machining. The Ni_54.1Ti_45.9 alloy’s surface characteristics are examined using a brass tool electrode and the WEDM (wire electrical discharge machining) technique, as well as the effects of changing process parameters. The purpose of this experiment was to use a one-factor-at-a-time method to determine how the WEDM variable parameters of wire feed rate (WF), pulse on time (T_ON), pulse off time (T_OFF), peak current (IP), wire tension (WT), affected the recast-layer thickness (RLT), and surface roughness. Following the results, it was determined that T_ON was the most effective parameter for the RLT.
