Parametric Optimization of CFRC Composite Drillingwith HSS Drillbyusing GRA

摘要

The Carbon Fiber Reinforced Carbon (CFRC) Composite material is gaining prominent position among the materials of modern period. The light weight and high strength composite is finding its way in various applications of Bio, Medical, Space and Defence fields. The growing use of this composite in aerospace and defence industries has prompted studies in developing technology for machining of these composites, especiallydrilling in recent years. This paper emphasizes the application of Grey Relational Analysis to determine the suitable values of drilling parameters of CFRC. The Grey theory provides solution to the uncertain, multi input and discrete data problems. AHigh Speed Steel tool is used for drilling the material on a CNC machine. The purpose of this paper is to find the significant parameters affecting the drilling of this unique material with the experimental results by using Grey Relational Analysis method.
