Carbon Fibre Reinforced Carbon (CFRC) Composite material is highly used in advanced industrial sector, especially in manufacturing of space shuttles and other expensive aerospace categories. The material's significant position and its growing importance has created interest among research community about the machining technology of this special material. This paper aims at finding the experimental drilling characteristics values of C-C composite by the combination of Taguchi method and Grey theory Technique. Manufacturing of good quality products at lower cost is the main objective of the modern industrial sector, and this is obtained by using optimal methods to the manufacturing conditions. This paper discusses about the use of Grey Theory to find the optimum drilling values. The experiments were conducted by using a Titanium Nitride coated Carbide drill tool on a carbon-carbon composite material plate with CNC Drilling Machine. This paper explains and demonstrates the influence of optimal set of characteristics, such as Spindle speed, Feed and Tool angle on the Delamination factors.Keywords

The composites are gaining significant position among various materials nowadays due to their unique features and properties. This Technological development in the materials sector has created interest among engineers and scientists to create new materials with different features and required properties. Among the various new developed materials, Carbon Fibre Reinforced Carbon (CFRC) composite material is occupying important place. This composite material is used mostly in the manufacturing of advanced structures like rockets, space shuttles, missiles, aircrafts etc. Generally these composites are very costly in nature and the addition of drilling cost of these materials makes them more costly. Hence the machining parameters are carefully selected, so that no drilling damage is caused during machining. The main objective of this paper is to find the optimal drilling parameters by using Taguchi method and the unique Grey Relational Analysis technique. The drilling experiments were carried out on a RCC composite plate with High speed steel tool on the VMC100 computer numerically controlled drilling machine, at the workshop of Anna university campus, Chennai, India.
