Abstract: Glass fiber reinforced plastic (GFRP) composite materials are widely used industrial, aerospace, and automotive sector. Its have excellent properties such as high strength to weight ratio, higher fatigue limit high stiffness to weight ratio, corrosion resistance and design flexibility. Drilling is one of the major machining operations that are carried out on fiber reinforced metal composite materials to the need for components assembly. There are many problems encountered when drilling Glass fiber reinforced plastic (GFRP) composites. These problems include delaminating of the composite, poor surface roughness and hole deviation. In present experimental investigation analyse the effect of various machining parameters i.e. cutting speed, the feed rate, and the drill diameter on the quality of the drilled holes. Hole deviation of each hole is measured with help of digital vernier calliper. Taguhis and ANOVA Technique have been employed to study the effect of the interactions between different drilling parameters on deviation of holes. After experiments suggests the optimal conditions for minimum hole deviation.
