Abstract
The objective of this paper is to determine the optimum values of drilling parameters of carbon fibre reinforced carbon (CFRC) composite material with the help of an experimental investigation, which includes the application of unique Grey theory method. The growing application of CFRC composites, which are popularly known as ‘carbon-carbon’ composites in Aerospace, Automobile, Defence and other advanced industries has prompted research studies to develop drilling technology of these special materials. The present work demonstrates the optimization process of multiple responses.The optimum values of drilling characteristics of these composites are calculated by the application of Taguchi method in combination with Grey Relational Analysis technique. The drilling experiments were carried with a High speed steel tool on a plate of carbon-carbon composite material on a CNC Drilling vertical Machining centre.
