Abstract

In this paper, an experiment is conducted to optimize the kerf width of wire electrical discharge machining (WEDM) on Aluminum hybrid composite with Zinc coated brass wire using Taguchi method. Aluminum metal matrix composites (MMCs) reinforced with silicon carbide particulate (SiCp) find several applications due to their improved mechanical properties for a wide variety of aerospace and automotive applications. The hybrid composite (Al6061/Sic/Graphite) is prepared by stir casting route. Parameters considered for this study is pulse on time, pulse off time ,peak current, gap set voltage, wire feed and wire tension. Taguchi orthogonal method is used to design the experiment (L27). In this analysis of results shows that kerf width is mostly influenced by the peak current.
