Title: Experimental Analysis of Hole Ovality in Drilling of Carbon-Carbon Composites
Abstract: The Carbon-Carbon (C-C) composite materials are logical candidates for the manufacture of space crafts and other advanced structures, due to their low density values. These materials are naturally expensive, and the machining cost increases the final product’s price. The literature availability on the machining, particularly with reference to drilling operation of these materials is very rare. Hence an experimental investigation has taken to study the hole quality of this ubiquitous carbon-carbon composite material. This paper presents a comprehensive analysis about the influence of process parameters on the ovality of the carbon-Carbon composite plate, which is measured with a coordinate measuring machine. The drilling experiments were carried with two different tools like HSS and TiN coated Carbide materials on a CNC drilling machine. The Point Angle, spindle speed and feed rate were chosen as process parameters, and their impact on the quality of drilled hole was analyzed with the help of Taguchi’s orthogonal array and ANOVA-TM software. A comparison was done between the performances of drilling by these two different tools.
