An Estimating the Effect of Process Parameters on Metal Removal Rate and Surface Roughness in WEDM of Composite Al6063/SiC/Al2O3 by Taguchi Method

Open access


The present study was focused on the fabrication of metal matrix and hybrid metal matrix composites through stir casting process. The Aluminium 6063 was used as base material and SiC/Al2O3 were used as reinforcement with varying weight %. The parametric study on a wire-cut electro discharge machine was carried out by using Taguchi Method. A statistical analysis of variance (ANOVA) was performed to identify the process parameters that were statistically significant. It was observed that the MRR decreases with increase in the percentage weight fraction of SiC and Al2O3 particles in the MMCs and HMMCs. Whereas, the surface roughness parameter increases with increase in the percentage weight fraction of SiC and Al2O3 particles due to the hardness of MMCs and HMMCs composites.
