Özet
Yapılan çalışmada, AA 6061-T6 alaşımının delinmesinde kesme parametresinin ve matkap helis açısının yüzey pürüzlülüğüne
(Ra), kesme sıcaklığına (T) ve enerji tüketimine (ET) etkileri deneysel ve istatistiksel olarak incelenmesi amaçlanmıştır. Delme
deney tasarımı Taguchi L27 ortogonal dizilimi kullanılarak hazırlanmıştır. Kesme parametreleri ve matkap helis açıları Ra, T ve
ET değerleri kullanılarak optimize edilmiştir. Deney sonuçları ilk olarak üç boyutlu grafikler ile değerlendirilmiştir. Elde edilen
veriler sinyal/gürültü oranı (S/N), varyans analizi (ANOVA), regresyon analizi ve doğrulama testleri yapılarak istatistiksel olarak
analiz edilmiştir. Bunlara ek olarak, Gri İlişkisel Analiz (GRA) kullanılarak Ra, T ve ET değişkenleri birlikte optimize edildi. Bu
çalışmanın sonucunda, optimum Ra, T ve ET değerlerine sırası ile A3B3C1, A1B1C1 ve A1B3C3 deney kombinasyonlarında
ulaşılmıştır. Ra, T ve ET üzerine en etkin parametre sırası ile 54.93% f, 52.02% kesme hızı (Vc) ve 68.12% ilerleme miktarı (f)
olduğu görülmüştür. GRA analizi sonucu Ra, T ve ET için optimum deney kombinasyonu A1B1C1 olmuştur. Analizler sonucu
geliştirilen matematiksel modeller ile tahmin edilen sonuçlar yüksek doğrulukta sonuçlar verdiği görülmüştür. Ayrıca matkap
uçlarında genel olarak BUE ve talaş yapışmaların oluştuğu görülmüştür.
In the study conducted aims to investigate the effects of cutting parameters and drill helix angle on surface roughness (Ra), cutting temperature (T) and energy consumption (SEC) in drilling AA 6061-T6 alloy experimentally and statistically. Drilling experimental design was prepared using Taguchi L27 orthogonal array. Cutting parameters and drill helix angles were optimized using Ra, T and ET values. Experimental results were first evaluated with three-dimensional graphics. Obtained data were statistically analysed by performing signal/noise ratio (S/N), analysis of variance (ANOVA), regression analysis and verification tests. In addition, Ra, T and ET variables were optimized together using Grey Relational Analysis (GRA). As a result of this study, optimum Ra, T and ET values were reached in A3B3C1, A1B1C1 and A1B3C3 experimental combinations, respectively. The most effective parameters on Ra, T and ET were found to be 54.93% f, 52.02% cutting speed (Vc) and 68.12% feed rate (f) respectively. The optimum experimental combination for Ra, T and ET was A1B1C1 as a result of GRA analysis. The results predicted with the mathematical models developed as a result of the analyses were found to yield high-accuracy results. In addition, it was observed that BUE and chip adhesion generally occurred in the drill bits.
