Bu çalışmada, Inconel 718 (IN718) süperalaşımının CNC tel erozyon tezgâhında işlenmesi sonucunda malzeme kesim yüzeyinde ölçülen Ra (ortalama yüzey pürüzlülüğü), Rq (kuadratik ortalama pürüzlülük) ve Rz (maksimum pürüzlülük) değerleri üzerinde işleme parametrelerinin etkileri araştırılmıştır. İşleme parametreleri; tel erozyon tezgâhı değişkenlerinden gerilim, tel ilerleme hızı ve dielektrik sıvı basıncı olarak belirlenmiştir. Deneylerde dielektrik sıvı olarak saf su ve tel olarak ise 0.3 mm pirinç tel kullanılmıştır. Çalışmanın amacı; en düşük Ra, Rq ve Rz değerlerini elde edebilmek için kesme parametrelerinin optimum değerlerini belirlemektir. Tel erozyon tezgâhı ile kesme işleminde işleme parametrelerinin optimizasyonu için, çok kriterli karar verme yöntemlerinden biri olan Gri İlişkisel Analiz (GİA) uygulanmıştır. Deneyler ve kullanılan parametrelerin seviyeleri Taguchi L9 (33) ortogonal dizisine göre tasarlanmıştır. Varyans Analizi (ANOVA) kesme parametrelerinin etki yüzdelerini belirlemek amacıyla kullanılmıştır. En yüksek etkiye sahip olan parametre Ra için %79.18, Rq için %84.05, Rz için ise %89.25 oran ile gerilim olarak tespit edilmiştir. En düşük Ra, Rq ve Rz değerleri sırasıyla 0.123 µm, 0.178 µm ve 0.740 µm olarak elde edilmiştir

Multi-Criteria optimization of surface roughness in wire EDM of Inconel 718 by Taguchi based gray relational analysis method

Öz

In this study, the effect of machining parameters on Ra (average surface roughness), Rq (quadratic average roughness) and Rz (maximum roughness) values were measured on the material cut surface as a result of machining Inconel 718 (IN718) superalloy on a CNC wire erosion machine were investigated. As the processing parameters; voltage, wire feed rate and dielectric fluid pressure were determined. In the experiments, pure water was used as the dielectric fluid and 0.3 mm brass wire was used as the wire. The aim of the study is to determine the optimum values of the cutting parameters in order to obtain the lowest Ra, Rq and Rz values. Gray Relational Analysis (GRA), which is one of the multi-criteria decision-making methods, has been applied for the optimization of the machining parameters in the cutting process with the wire erosion machine. The experiments and the levels of the parameters used were designed and optimized according to the Taguchi L9 (33) orthogonal array. Analysis of Variance (ANOVA) was used to determine the effect percentages of the cut-off parameters. The parameter with the highest effect was determined as voltage with a ratio of 79.18% for Ra, 84.05% for Rq, and 89.25% for Rz. The lowest Ra, Rq and Rz values were obtained as 0.123 µm, 0.178 µm and 0.740 µm, respectively.
