Abstract: Nowadays, The Reinforced Carbon-Carbon (RCC) Composite material is gaining significant place among the various engineering materials. The light weight and high strength composite is finding its way in recent advanced applications like Medical, Space, Defence and Bio related fields. The growing use of this composite in these advanced industries has created inquisitiveness among researchers and prompted them to study about developing technology for machining of these composites, especially with respect to the drilling operation. Drilling is the most frequently used material removal process and the production of a good quality hole will enhance the quality of the final product. The quality of hole of a composite depends on delamination mechanism and the increase in delamination factor reduces the quality of the product. This paper presents the application of Taguchi method to determine the suitable values of drilling parameters of RCC for the minimization of delamination factor. Taguchi technique emphasizes the importance of studying the response characteristic variation using S/N ratio, resulting minimization of variation in quality characteristic due to uncontrollable parameters. High Speed Steel tool is used for drilling the work piece material, i.e. RCC composite on a CNC machine.
