Optimization of Processing Parameters of AISI 316 Ti Stainless Steels

Abstract

In this study; AISI 316Ti stainless steels have been used as test materials because of  their use in the manufacturing sector with high mechanical properties, good corrosion resistance and low thermal conductivity. The effect of feed rate, cutting depth and cooling technique on surface roughness and cutting forces were investigated. In the experiments 0.1, 0.2 and 0.3 mm /rev feed rate, 0.5, 1 and 1.5 mm cutting depth and dry, MQL and CO₂ cooling conditions were used variably. Taguchi technique was used for the experimental design of the turning process. Cutting speed was kept constant. Taguchi technique was used for the experimental design of the turning process.  By way of this technique, optimum values were obtained with few experiments. In addition, Grey Relational Analysis (GRA) method was used to determine the optimal parameters level. The optimal GRA value was obtained from experiment number 1 as 0.94. Accordingly, for the lowest surface roughness and cutting force, the cutting depth and feed rate values should be kept to minimum.

AISI 316 Ti Paslanmaz Çeliklerin İşleme Parametrelerinin Optimizasyonu

Abstract

Bu çalışmada; mekanik özelliklerinin yüksek, korozyon direnci iyi olması ve düşük ısıl iletkenlikleri ile imalat sektöründe önemli bir kullanım sahasına AISI 316Ti paslanmaz çelikler deney malzemesi olarak kullanılmıştır. Tornalama da ilerleme oranının, talaş derinliğinin ve soğutma sisteminin yüzey pürüzlülüğüne ve kesme kuvvetlerine etkisi araştırıldı. Deneylerde 0.1, 0.2 ve 0.3 mm/dev ilerleme oranı, 0.5, 1 ve 1.5 mm talaş derinliği ve kuru, MQL ve CO₂ işleme parametreleri değişken olarak kullanılmıştır.  Kesme hızı sabit tutulmuştur. Tornalama işleminin deneysel tasarımı için Taguchi tekniği kullanıldı. Bu teknik sayesinde az sayıda yapılan deneyle optimum değerler elde edilmiştir. Ayrıca en iyi parametre seviyelerinin belirlenmesi için Gri İlişki analizi metodu kullanıldı. En ideal GRA değeri 0,994 olarak 1’nolu deneyden elde edilmiştir. Buna göre en düşük yüzey pürüzlüğü ve kesme kuvveti için talaş derinliği ve ilerleme değerlerinin minimum tutulması gerekmektedir.
