Influence of Milling Process Parameters on Machined Surface Quality of Carbon Fibre Reinforced Polymer (CFRP) Composites Using Taguchi Analysis and Grey Relational Analysis

The article presents the milled surface quality of Uni-Directional Carbon Fibre Reinforced Polymer (UD-CFRP) composites from Taguchi’s and grey relational analysis. novelty is demonstrating possibility detecting defects in polymer during milling using SEM material used for this study UD-CFRP composite laminates made by hand-layup process. All operations were carried out a solid tungsten carbide end tool experiments conducted on CNC machine. Taguchi L9, 3-level orthogonal array was considered experimentation. Analysis Variance (ANOVA) to explore significance each individual input process parameters multiple performance characteristics. Optimal are thoroughly validated grade achieved analysis multi Finally, experimental results correlated analyzed with scanning electron micrographs Scanning Electron Microscope (SEM).
