Abstract
Abstract AA 7075 has been recognized as a highly suitable material for numerous applications in engineering due to its exceptional characteristics, including enhanced ductility and decreased susceptibility to fatigue. It is widely used in the aerospace industry and shows promise for several other technical applications. Its exceptional corrosion resistance makes it the favoured choice for many applications. Producing complex-shaped components using traditional machining methods is difficult. Various advanced machining techniques have been developed to prevent such difficulties. Wire Electrical Discharge Machining (WEDM) is a distinct technique that belongs to the broader classification of Electrical Discharge Machining (EDM). This study utilizes Taguchi’s methods to investigate the Wire Electrical Discharge Machining (WEDM) of AA 7075 aluminum alloy. This study utilizes a natural dielectric medium in order to reduce the negative impacts on the environment. The investigation includes a wide range of performance indicators, including material removal rate, surface roughness, and tolerance errors. ANOVA is a statistical method used to assess the importance of process factors. The outcomes of this investigation are much helpful for the manufacturers to make the quality parts precisely.
