Özet:

 The use of fiber reinforced composite materials FRP has increased in many areas. These materials need to be processed with some machining methods according to their usage areas, but their machinability is difficult. In this study, surface roughness SR, delamination factor Fd and thrust forces were investigated in the drilling of glass fiber reinforced composite material GFRP produced by pultrusion with a coated and uncoated drill. Microstructures of chips formed during drilling were investigated and their effects on surface roughness were determined. Three different cutting speeds 60, 70, 80 mmin and feed rates 0.06, 0.09, 0.12 mmmin were selected as machining parameters. At the end of the study, it was found that feed rate had a more significant effect on surface roughness, delamination factor and thrust force. It was observed that as the cutting speed increased, the surface roughness, thrust force and delamination factor decreased. The lowest thrust force and Fd occurred at a cutting speed of 80 mmin and a feed rate of 0.06 mmmin. However, the lowest SR was obtained at a cutting speed of 70 mmin and a feed rate of 0.06 mmmin.Better results were obtained with TiN coated drills compared to uncoated drills.

 Fiber takviyeli kompozit malzemelerin birçok alanda kullanımı artmıştır. Bu malzemeler kullanım alanlarına göre bazı talaşlı imalat yöntemleri ile işlenmesi gerekmektedir fakat işlenebilirlikleri zordur. Bu çalışmada pultrüzyon ile üretilmiş cam fiber takviyeli kompozit malzemenin kaplamalı ve kaplamasız matkap ile delinmesinde yüzey pürüzlülüğü, delaminasyon faktörü ve itme kuvvetleri incelenmiştir. Delme sırasında oluşan talaşların mikro yapıları incelenmiş ve yüzey pürüzlülüğüne etkileri belirlenmiştir. İşleme parametreleri olarak üç farklı kesme hızı 60,70, 80 mdk ve ilerme oranı 0.06, 0.09, 0.12 mmdk seçilmiştir. Çalışma sonunda, ilerleme oranı yüzey pürüzlülüğü, delaminasyon faktörü ve itme kuvveti üzerinde daha belirgin etki yaptığı bulunmuştur. Kesme hızı arttıkça yüzey pürüzlülüğü, itme kuvveti ve delaminasyon faktörünün azaldığı görülmüştür. İtme kuvveti ve delaminasyon faktörü en düşük 80 mdk kesme hızı ve 0.06 mmdk ilerleme oranında oluşmuştur. Ancak en düşük yüzey pürüzlülüğü 70 mdk kesme hızı ve 0.06 mmdk ilerleme oranında çıkmıştır. TiN kaplı matkaplarda kaplamasız matkaplara kıyasla daha iyi sonuçlar elde edilmiştir.
