Abstract
Fiber reinforced polymer (FRP) composites are being used in a variety of areas. These materials need to be processed with some machining methods according to their usage areas, but their machinability is difficult. In this study, drilling is performed on glass fiber reinforced polymer (GFRP) composite produced by pultrusion with coated and uncoated drill. Then, surface roughness (SR), delamination factor (Fd) and thrust forces were investigated. Microstructures of chips formed during drilling were investigated and their effects on surface roughness were determined. Three distinct feed rates and cutting speeds were selected as machining parameters. Investigations showed that feed rate had a more significant effect on surface roughness, delamination factor and thrust force. It was understood that when the cutting speed increased, the surface roughness, thrust force and delamination factor decreased. Better results were obtained with TiN coated drills compared to uncoated drills.
