Abstract

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.
