Summary, etc. Machining performances are strongly influenced by vibration which occurs due to the dynamic nature of machine toolstructures. A self excited vibration commonly known as chatter is frequent debacle occurs during milling operations whichcause worsening outcomes such as excessive tool wear, poor surface finish and reduced tool life. In this paper an effort hasbeen tried to optimize the machining and geometrical parameters for reduced vibration using Taguchi method with greyrelational analysis during end milling of Al356/SiC metal matrix composites. The twin channel piezoelectric accelerometerhas been used to measure vibration. Acceleration amplitudes at two different positions, one in spindle and another in workpiece holder have been recorded for each experiment. Analyses of variance (ANOVA) have been applied to find theprominent parameters and the optimal parameter combination for best average response and signal to noise (S/N) ratio.Grey relational analysis has been implemented to find the optimal permutation of machining and geometrical parameters byconsidering both responses (acceleration amplitude taken at two different positions) simultaneously. Confirmation testsestablished that the grey-based Taguchi method has been successful in optimizing the process parameter for reducedvibration.
