Machinability Examination on Nylon-6 GFRP Composite with Abrasive Water Jet Machining

Abstract

This work is aimed to understand the influence of Abrasive Water Jet Machining parameter on surface roughness of the composites. Extrusion process is used to fabricate the Nylon 6 – GFRP composites. L27 orthogonal array is employed to conduct the experimental studies. Three levels and three parameter namely applied pressure; standoff distance and transverse feed are used to study the effect on surface roughness. Taguchi method is employed to determine the optimal combination of the machining parameter. The maximum applied pressure, low transverse speed and standoff distance is beneficial for reducing the surface roughness. ANOVA is also employed to determine the contribution of each process parameter on surface roughness and it is found that standoff distance plays important role in reducing the surface roughness followed by transverse speed and applied pressure.
