Abstract

The Technological advancement in materials division has created curiosity among engineers, scientists and researchers to develop new materials with the required properties. One such material is Carbon Fibre Reinforced Carbon (CFRC) composite material, which is used mostly in the fabrication of advanced structures like space shuttles, missiles, airbuses etc. Generally these composites are very expensive and the addition of machining cost of these materials makes them more expensive. Hence careful selection of proper machining parameters is required to machine these special composites. The prime objective of this paper is to investigate experimentally to find the optimal drilling parameters by using Grey Relational Analysis technique. The drilling experiments were carried out on a CFRC composite plate with High speed steel tool on the VMC100 computer numerically controlled drilling machine, which is in the workshop of Anna university campus, Chennai, India.
