Abstract

This paper investigates the effect and parametric optimization of process parameters for milling of GFRP (Glass Fiber Reinforced Polymer) composites using Grey Relational Analysis. Experiments were conducted using helix angle, spindle speed, feed rate, depth of cut and fibre orientation angle as typical process parameters. The grey relational analysis was adopted to obtain grey relational grade for milling process with multiple characteristics, namely Machining Force and Material Removal Rate (MRR). Analysis of variance (ANOVA) was performed to get the contribution of each parameter on the performance characteristics and it was observed that helix angle and fibre orientation angle were the most significant process parameters that affects the milling of GFRP composites. The experimental results reveal that, the helix o angle of 45 , spindle speed of 3000rpm, feed rate of 1000mm/min, depth of cut of 2mm and fibre orientation angle of o 15 is the optimum combination for lower machining force and higher material removal rate. The experimental results for the optimal setting show that there is considerable improvement in the process.
