Optimization Of Process Parameters In Drilling Jute Fibre Reinforced Hybrid Nano Composites

Abstract: Natural fibre reinforced composites have been the topic of recent research. Addition of nanofillers has been reported to enhance the performance of these polymeric composites even at small loading. The composites are machined to be employed in desired application. The machining process has to be optimized for finding out the combination of parameters that offer high-quality output. The present paper deals with the optimization of drilling of jute fibre reinforced, graphene filled epoxy nanocomposite. Delamination factor, thrust force, torque, surface roughness, circularity and cylindricity have been measured and optimized. Grey Relational Analysis (GRA) was used to optimize the process parameters. The weight value of each performance characteristic was found out using Principal Component Analysis (PCA). The optimal combination of drilling parameters was found out and compared with the initial value and gain obtained has been reported.
