Abstract

In recent days composites are finding wide application in all fields because of their specific properties. Drilling is the most common machining operation performed on composites and the quality of hole has an important bearing on its applications. The quality of the drilled hole is mainly defined by delamination, surface roughness, and cylindricity, and it depends upon process variables such as thrust and torque. This paper deals with the study of the influence of process parameters on the quality of hole in drilling of Glass Fiber Reinforced Polymer (GFRP) composites. The results have shown that the drill geometry has major influence on the quality of drilled hole in comparison to drill size, work-piece thickness, volume fraction, fiber orientation, speed and feed.
