This paper presents an experimental investigation of the influence of drilling conditions on surface finish of
hole during drilling of Al/SiC-MMC. Taguchi method and Analysis of variance (ANOVA) is employed to investigate the
influence of spindle speed, feed rate and drill bit material (Carbide and HSS) on surface finish of hole. Through various
graphical representations it can be concluded that lower spindle speed and lower feed rate are the suitable parameters for
better surface finish for carbide drill. Higher spindle speed and higher feed rate are suitable parameters for HSS drill.
