Wire electrical discharge machining is a very accurate thermal machining technique employed for the exact shaping of objects characterized by varying degrees of hardness or complex geometries. This technique has notable efficacy in the machining of components possessing sharp edges that pose difficulties in their formation using traditional machining techniques. The wire electrical discharge machining (WEDM) process is an efficient technology that utilizes the conventional EDM sparking phenomenon. It utilizes an extensively established non-contact method to eliminate material. The current research utilizes Taguchi approach to investigate the impact of different wire electrical discharge machining (WEDM) process parameters on the kerf width of EN36B steel. Four essential process parameters, namely pulse on time (Ton), pulse off time (Toff), current (Ip), and wire speed (WS), are chosen. Each parameter has three levels. The objective is to minimize the width of the kerf. A L27 orthogonal array (OA) is employed to systematically examine the impact of the selected input parameters and their potential interactions. Afterwards, a signal-to-noise (S/N) ratio study is performed to determine the best settings for reducing the kerf width within the stated experimental range. Furthermore, a statistical analysis known as analysis of variance (ANOVA) is performed to evaluate the significance of the process parameters and their interactions in controlling the kerf width of EN36B steel. In order to ascertain the significance of the selected design, a validation test is ultimately conducted. The findings indicate a notable improvement, as evidenced by the signal-to-noise ratio (S/N ratio) of the kerf width under optimal circumstances, which demonstrates a 14% enhancement in comparison to the initial condition.
