Analysis and optimisation of machinability behaviour of CFRP composites using fuzzy logic

Abstract

Purpose– The purpose of this paper is to analyse and optimise the machinability behaviour of Carbon Fibre Reinforced Polymer (CFRP) composites with multiple performance characteristics using the Taguchi method with fuzzy logic.Design/methodology/approach– A multi-response performance index (MRPI) was used for optimisation. The machining parameters,viz., tool geometry (helix angle of the endmill cutter), spindle speed, feed rate and depth of cut, were optimised with consideration of multiple performance characteristics,viz., machining force and material removal rate.Findings– The results from confirmation runs indicated that the determined optimal combination of machining parameters improved the performance of the machining process.Originality/value– The machinability behaviour of CFRP composites during milling of CFRP composites using Taguchi method with fuzzy logic has not been previously analysed.
