An Effort for Identifying Suitable Machining Range During Drilling of a Novel Al-Based Composite Using Electric Discharge Machine

Abstract

Various aluminium-based metal matrix composites (MMCs) have recently attracted significant interest and increased popularity. This is because of its’ outstanding mechanical properties, which makes it a very popular material since it has various applications in industries that need strong yet lightweight materials with high strength. Researchers have made great progress in the mechanical properties of Al-based composites. In any case, it becomes imperative to improve the mechanical characteristics of the given material on demand. The current work aims at producing these aluminium-based MMC and, subsequently, precise machined EDM. It is an uncommon machining process typically known to produce tough materials of any arbitrary geometry. EDM is a technique that involves the fine-tuning of the electrode material, pulse length, and pulse current to yield the best results without causing much damage to the workpiece and maintaining its mechanical strength. Lastly, the research comprises an elaborate discussion on the optimum process parameters and experimental results about the effective manufacture of superior strength aluminium-based composites as well as their accurate electro-discharge machining. These results provide valuable information on making and machine metals for various technical uses across construction, mechanical engineering and electronics manufacturing industries.
