Keywords:
Al-SiC Composites, Turning, Surface Roughness, Material Removal Rate, OptimizationAbstract
This study presents an experimental investigation of the effects of cutting speed, feed rate, depth of cut and volume fraction of SiC particles on surface roughness and material removal rate in turning of Al-SiC composites. A plan of experiments based on Taguchi method was implemented for machining of Al-SiC composites using tungsten carbide tool. Analysis of Variance was employed to find out the contribution and influence of each parameter on surface roughness and material removal rate. In addition to ANOVA, the multiple performance characteristics were also analyzed using Grey relational approach and Taguchi response table by determining grey relational coefficients and grades. The optimum level of parameters setting in machining of Al-SiC composites for minimum surface roughness and maximum material removal rate was obtained at 200 m/min of cutting speed (level 3), 0.1 mm/rev of feed rate (level 2), 1 mm of depth of cut (level 2) and 10% of volume fraction of SiC (level 2).
