Investigation of the Machinability Characteristics on Delamination during Drilling of Hybrid Reinforced Epoxy Polymer using Taguchi Approach

Abstract

Nowadays quality plays a vital role in all the products. Hence, the development in manufacturing process
focuses on the fabrication of composite with high dimensional accuracy and also incurring low manufacturing cost. The
composites, especially epoxy polymer composites have important advantages because of its superior mechanical
properties such as high strength to weight ratio, high wear resistance, corrosion resistance, electrical resistance, and
etc. It can replace the traditional materials for manufacturing different components with required properties. The major
applications of these composites are in electronic industry, automobile industry and aerospace industry. But machining
of these composites is dissimilar to conventional metals due to their isotropic nature and in-homogeneity. Major
drawbacks of these composites in machining are fiber pull out, delaminating and burring of fibers. So, appropriate
selection of process parameters is an important concern in machining of GFRP composites. So, appropriate selection of
process parameters is an important concern in machining of GFRP composites. This work mainly focuses on assessing
the effects of process parameters i.e. spindle speed, feed on Delamination factor in drilling of GFRP composites.
