Bu çalışmada, [0º/90º]s fiber oryantasyon açısında üretilmiş olan karbon elyaf takviyeli polimer (KETP) kompozit malzemenin farklı matkap uçlarıyla 5 eksen CNC kontrollü dik işleme merkezinde delinmesi sonucu elde edilen delaminasyon faktörü (Fd) değerleri analiz edilmiştir. Taguchi yöntemi ile deneysel tasarım uygulanmıştır. Delme deneyleri Minitab 19 yazılımı kullanılarak Taguchi L18 ortogonal dizinine göre yapılmıştır. Deney sonuçları sinyal/gürültü (S/N) oranı esas alınarak değerlendirilmiştir. Kontrol faktörleri olarak iki farklı matkap ucu (HSS ve karbür), üç farklı iş mili devri (750, 1000, 1500 dev/dak) ve üç farklı ilerleme hızı (0.05, 0.10, 0.15 mm/dev) seçilmiştir. Varyans analizi (ANOVA) uygulanarak kontrol faktörlerinin Fd üzerindeki etki seviyeleri bulunmuştur. ANOVA analizi ile %94.85 güvenirlik seviyesi elde edilmiştir. En düşük Fd değeri karbür matkap ucu kullanılarak, 1500 dev/dak iş mili devri ve 0.05 mm/dev ilerleme hızında 1.3905 olarak tespit edilmiştir.
