Investigation of Drilling Characteristics of Neem-Fiber Laminate Composite

Abstract

In this investigation, a composite amalgamating neem fiber and an epoxy resin compound as the binding agent was synthesized. Neem fiber's inclusion stems from its remarkable attributes, notably its exceptional tensile strength, flexural properties, and resistance to saltwater corrosion. The performance evaluation of this neem composite was conducted through rigorous trials using a vertical drilling apparatus, varying spindle speeds, feed rates, and drill dimensions. Employing the Taguchi approach within an L27 orthogonal array setup, diverse combinations of factors were systematically generated. Parameters encompassing metal removal rate, thrust force, torque, peel up delamination, and push out delamination were amalgamated to derive the Signal-to-Noise (SN) ratio, serving as a comprehensive metric for the test outcomes. Subsequently, the Taguchi technique's results will undergo further refinement and will be subjected to a grey relational grading process for enhanced precision and analysis.
