Analyzing Process Capability of Drilling on Glass Fiber Reinforced Polyester (GFRP) Composites with Taguchi Loss Function

Article Preview

Abstract:

The delamination is a major problem associated with the drilling of chopped glass fiber reinforced polyester (GFRP) composites. It reduces the structural integrity of the material, results in poor assembly tolerance and has the potential for long term performance deterioration. Thus it is important to evaluate the process capability of drilling on this material. It will thereby reveal the spectrum of delamination to be accepted from the view point of process capability for a chosen range of material thickness, drill diameter, speed and feed rate combinations. In the present analysis, therefore, Taguchi loss function is derived for the particular process based on the experimental data. Process capability index is then evaluated. The range of delamination factor is determined based on the consideration that process capability index should be one or more. The results are presented.
