Investigations on Wire Electrical Discharge Machining of Magnesium Alloy for Automobile Parts

Magnesium alloy, known for its high strength and lightweight properties, finds widespread utilization in various technical applications. Aerospace applications, such as fuselages and steering columns, are well-suited for their utilization. These materials are frequently employed in automotive components, such as steering wheels and fuel tank lids, due to their notable corrosion resistance. The performance of magnesium alloy components remains unimproved by normal manufacturing methods due to the inherent characteristics of the material. This work introduces a contemporary approach to fabricating complex geometries through the utilization of Wire-Electro Discharge Machining (WEDM). The material utilized in this study was magnesium alloy. The investigation also considered the input parameters associated with the Wire Electrical Discharge Machining (WEDM) process, specifically the pulse duration and peak current. The findings of the study encompassed the material removal rate and surface roughness. Taguchi successfully employed a single aspect optimization technique to ascertain the ideal combination that would enhance the efficacy of the WEDM process. The findings of the investigation revealed that the proposed technique significantly improved the efficiency of the WEDM approach.
