AISI 1040 çeliği, makine ve imalat sanayinde yaygın olarak kullanılan ve çeşitli makine parçası,
otomotiv parçası, kalıp ve diğer birçok alanda yer alan bir malzemedir. Son yıllarda işleme alanındaki
teknolojik gelişmeler, işleme performansını etkileyen birçok soruna yol açmıştır. Delme en önemli işleme
operasyonlarından biridir. Bu çalışmada kesme hızı (15, 20 m/dak), diş başı ilerleme (0.1, 0.15 mm/diş),
matkap tipi (HSS-E, HSS-E TiN kaplı), delme stili (standart, gagalama) ve soğutma tipi (sıvı, hava) gibi
delme parametrelerinin etkisi AISI 1040 çeliği üzerinde incelendi. Parametrelerin yüzey pürüzlülüğü
üzerindeki etkileri araştırıldı. Deneyler L8 ortogonal dizisine göre planlandı. Taguchi’nin Sinyal/Gürültü
analizi ile optimum koşullar bulundu. Sonuçların ölçülen/hesaplanan değerlerinin dağılımını belirlemek
için olasılık analizi yapıldı. Son olarak, optimizasyonun başarısını kontrol etmek için doğrulama testleri
yapıldı. Yüzey pürüzlülüğü için en uygun koşullar A1B2C2D1E2'de gözlenmiştir (yani, kesme hızı:
15m/dak, diş başı ilerleme: 0,15mm/diş, soğutma tipi: sıvı, delme tipi: standart ve matkap tipi: HSS-ETiN
kaplı).

EXPERIMENTAL AND STATISTICAL INVESTIGATION OF DRILLING OF AISI 1040 STEEL AT DRY AND WET CONDITIONS

Öz

AISI 1040 steel is widely used in the machinery and manufacturing industries and is used
in a variety of machine parts, automotive parts, molds, fixtures and many other areas. Technological
developments in the field of machining in recent years have led to many problems affecting machining
performance. Drilling is one of the most important machining operations. In this study effect of drilling
parameters such as cutting speed (15, 20 m/min), feed rate (0.1, 0.15 mm/tooth), type of drill (HSS-E, HSSE
TiN coated), drilling type (standard, pecking) and cooling type (liquid, air) were examined on AISI 1040
steel. Parameters’ effects on surface roughness were investigated. Experiments were planned according to
L8 orthogonal array. Optimum conditions were found via Taguchi’s Signal/Noise analysis. Probability
analysis was performed to discover the distribution of the measured/calculated values of the results.
Lastly, confirmation tests were conducted to control the success of the optimization. The optimal
conditions for surface roughness were observed at A1B2C2D1E2 (i.e., cutting speed: 15m/min, feed rate:
0.15mm/tooth, cooling type: liquid, drilling type: standard, and type of drill: HSS-ETiN coated).
