INCONEL 600 SÜPER ALAŞIMININ TORNALANMASINDA İŞLEME PARAMETRELERİNİN OPTİMİZASYONU
Bu çalışmada Taguchi metodu esas alınarak kesici takım kaplama malzemesinin ve kesme hızının kesme kuvvetleri ve yüzey pürüzlülüğü üzerindeki etkileri araştırılmıştır. Teğet kesme kuvveti (Fz), asıl kesme kuvveti olarak kabul edilmiş ve kriter olarak alınmıştır. İşleme parametrelerinin etkileri L18 Taguchi deney tertibi ile araştırılmıştır. Optimum kesme şartları, ''daha küçük daha iyidir'' yaklaşımına göre kesme kuvveti ve yüzey pürüzlülüğü için sinyal-gürültü (S/N) oranı hesaplanarak tespit edilmiştir. Varyans (ANOVA) analizi ve sinyalgürültü (S/N) oranı sonuçları kullanılarak parametrelerin, yüzey pürüzlülüğü ve kesme kuvvetleri üzerindeki etkileri istatistiki olarak araştırılmıştır. Kesme kuvveti FZ (N)'nin üzerinde kesici ve ilerlemenin etkisi daha yüksek iken, ortalam yüzey pürüzlülüğü Ra (μm)nın üzerinde ilerleme ve kesme hızının etkisi daha yüksek görülmüştür.
OPTIMIZATION OF TURNING MACHINIG PARAMETERS IN INCONEL 600 SUPER ALLOY
In this paper, the effects of cutting tool coating material and cutting speed on cutting forces and surface roughness were investigated on Taguchi experimantal design. Main cutting force, FZ is considered to be cutting force as a criterion. The effects of machining parameters were investigated using Taguchi L18 ortogonal array. Optimal cutting conditions were determined using the signal to-noise (S/N) ratio which is calculated for average surface roughness and cutting force according to thesmaller is betterapproach. Using results of analysis of variance (ANOVA) and signal-to-noise (S/N) ratio, effects of parameters on both average surface roughness and cutting forces were statistically investigated. It has seen that while cutting tool and feed rate has higher effect on average surface roughness.
