Multi response optimization of drilling performance of MWCNT filled banana-glass fibre reinforced composite

Natural fibres reinforced composites (NFRC) with their extended account of portion mankind are extremely significant in a broad variety of applications, and they battle and co-exist in the twenty-first century with man-made fibres, particularly as far as excellence, sustainability and cost-cutting measure of production are troubled. Numerous researchers have synthesized NFRCs using various natural fibres as well as matrix materials. Though, real-world applications of NFRCs involve some machining operations in order to complete the assembly of the parts. In this work, a technique based on the factorial design-based desirability analysis is used to determine the desired optimum machining parameters for minimum delamination, thrust force and surface roughness in drilling of MWCNT filled banana-glass natural fibres reinforced composites. The speed, federate, wt% MWCNT and point angle of drill are the most important parameters that characterize the machining operation and have been selected for investigation. Results indicated that point angle is playing major role on the responses followed by feed rate.
