For industrial applications, the ceramics composites are machined in large scale using end milling process. Due the abrasive reinforcement particle of composite, the failure in tool life and surface quality are possible. This research work focuses on developing the mathematical models of cutting force (FR), Metal Removal Rate (MRR) and surface roughness (Ra) and to optimize it. The Response Surface Methodology (RSM) with the L31 empirical model was used for conducting the basic trials on Al/SiC composites of various compositions. The XRD, EDS, optical microscopic images of Al/SiC composites were analyzed and the SEM morphology of the machined samples was studied. The models developed for predicting responses were tested by analysis of variance (ANOVA) to evaluate its adequacy. The optimal configuration of machining parameters was identified which yields 31.9326 mm3/s, 1.4443 μm and 41.4364 N of MRR, Ra and FR respectively. © Copyright 2015 American Scientific Publishers All Rights Reserved.
