- In the current investigation the influence of drilling process parameters such as cutting speed, feed rate and point angle in affecting the surface roughness of Al Metal Matrix Composites (AA7075 5 wt% SiC ) was investigated. Al MMC was synthesized using stir casting technique. Experiments (Drilling process) was carried out using taguchi L9 array. Drilling process parameters were considered as the factors in affecting the response ( surface roughness). Process parameters were varied at three levels ( Cutting speed 600,900 & 1200 rpm, feed rate -0.5.0.8 & 1.1 mm/rev and point angle – 90o,115o & 140o ). Drill diameter was kept constant at 10 mm. Analysis of Variance (ANOVA) indicated that the cutting speed ( 98.95%) had largely influenced the surface roughness of the composite. Surface roughness found to decrease with increasing cutting speed Keywords: Al MMC SiC- factors Surface roughness ANOVA – S/N ratio
