Abstract: Metal Matrix Composites (MMCs) are widely used in variety of engineering applications. The usage of aluminium based composites in modern automobile and aerospace sectors is enormous due to superior Mechanical properties as compared to other materials. In this investigation Taguchi and Response surface methodologies have been used to minimize the cutting force in turning of AA7068/TiC MMCs. The experiments are planned and executed according to central composite design technique on all geared lathe machine using TiCN-Al2O3 tool insert (KCP05). The process parameters used are wt. % of TiC, cutting speed, feed and depth of cut. The objective of this experiment is to optimize the process parameters and evaluate the effect of process parameters. A second-order mathematical predictive model has developed between the process parameters & cutting force based on response surface methodology (RSM). The conclusions of this experiment is give that the most influenced process parameter for cutting force is depth of cut (d) and is followed by wt.% of TiC. Precision is observed between the predicted values and experimental results; therefore, the evaluated model is fit to predict the cutting force in machining of AMMCs.
