Keywords:
Al-SiC-Gr Composites, Turning, Material Removal Rate, RSM, ANOVAAbstract
Metal matrix composites have found broad application in industrial fields where parts are required to be light and heat-resistant or wear-resistant properties. Machining of Al-SiC-Gr has become increasingly important in many engineering industry subsequently the prediction of material removal rate is also a significant response in turning conditions. In this experimental study, turning operation was carried out on all gear lathe using carbide cutting tool on Al-SiC-Gr composites and its material removal rate was measured by varying the process parameters. The parameters considered were: combined equal weight fraction of SiC-Gr particulates, cutting speed, depth of cut and feed rate. The central composite design had been utilized to plan the experiments and response surface methodology (RSM) was employed for developing experimental model. Analysis on machining characteristics of Al-SiC-Gr hybrid composites was made based on the developed model.
