Investigation of Drilling Characteristics of Abaca-Neem Fiber Laminate Composite

Abstract

In this work, an epoxy resin combination is used as the bonding agent to create a composite made of abaca and neem fibre. The combination of abaca and neem fibre is used because it has outstanding tensile and flexural characteristics as well as salt water corrosion resistance. Using a vertical drilling machine with different spindle speeds, feed rates, and drill diameters, the abaca neem composite is put to the test. The Taguchi technique is used to generate factor combinations and is implemented in an L27 orthogonal array arrangement. The SN ratio is produced for test data acquired by combining parameters for metal removal rate, thrust force, torque, along with peel up delamination and push out delamination. To further enhance and provide a grey relational grade of the Taguchi technique results, grey relational analysis is used. The ANOVA table is generated in order to determine the significance and contribution percentage of each component. The spindle speed, followed by feed rate and drill bit diameter, was determined to have the greatest impact on the drilling process. The regression equation is produced for each of the influencing variables in order to forecast the future behaviour of the dependent and independent variables.
