— Machining of composite materials is difficult to carry out due to the anisotropic and nonhomogeneous structure of composites and to the high abrasiveness of their reinforcing constituents. This typically results in damage being introduced into the work piece and very rapid wear development in the cutting tool. Conventional machining processes such as turning, drilling or milling can be adapted to composite materials, provided proper tool design and operating conditions are maintained. The present work also describes the machining (drilling) of GFRP composites with the help of Step drill of three sets, with three different speeds. Results revealed that 8-4 mm step drill showed better machining characteristic than the other two 12-8 mm and 10-6 mm step drills. The ZnS Filled GFRP composites had better performance than TiO2 filled GFRP Composites. Index Terms— Drilling; Polymer-matrix composites; Thrust force; Delamination.
