Optimization of Process Parameters during Milling of Friction Stir Processed GFRP Composites

Article Preview

Abstract:

In this study, GFRP plates were friction stir processed at three different feed rates (15 mm/min, 20 mm/min and 25 mm/min) and at a constant spindle speed of 1500 rpm with an aim to enhance their microstructural properties. The friction stir processed plates were then subjected to milling with solid carbide K6 end mill tools. Millings trials were carried out using a Taguchi’s L9 orthogonal array under three input parameters such as cutting speed, feed and depth of cut each having three levels. The statistical significance of the process parameters was estimated using signal to noise (S/N) ratio and Analysis of Variance (ANOVA). The study showed that cutting speed during milling and feed rate during FSP contributed to the overall performance which was assessed in terms of surface roughness and delamination factor.
