One of the unconventional machining techniques is wire EDM. The objective of the current inquiry is to analyse the surface roughness of composites made of aluminium and silicon carbide that contain silicon carbide particles. Conventional machining techniques are now being replaced by non-traditional machining techniques because of the rising demands for high surface finishes and the processing of complicated form geometries. This useful technology of the WEDM procedure is based on the typical EDM sparking phenomenon and makes use of the commonly used non-contact material removal method. The finest choice for producing micro-scale parts with the highest level of dimensional precision and surface finish quality is WEDM, which has been utilized for generating tools and dies in a straightforward manner. To determine their influence on the output parameter, namely the surface roughness of aluminium/SiC composites containing SiC particulates, it has been investigated how different WEDM parameters such as pulse on time (Ton), pulse off time (Toff), servo voltage (SV), and wire tension (WT) affect each other. To explore the effects of the factors and afterwards anticipate sets of optimal parameters for minimizing the surface roughness, an experimental plan is carried out using the Taguchi technique. Moreover, Analysis of variance (ANOVA) is used to determine how specific elements affect the work piece's surface roughness.
