In this work, the effect of brass wire coated with zinc as electrode wire towards maximizing MRR and minimizing SR for the considered input parameters was studied in elaborate during profile cutting of tool steel AISI D3. Experiments were designed based on the L18(21 ,37 ) Taguchi’s orthogonal array considering cutting speed, Ton and Toff, wire tension, servo feed rate and voltage, current and electrode feed rate. The outputs MRR and SR were analyzed and optimized using Grey Relational Analysis (GRA) simultaneously. For both SR and MRR, the drawn chart shows that, the raw data’s lies within upper and lower control limits. The optimum input conditions obtained for higher MRR and lower SR were: 75% of cutting speed, 128 µsec of Ton, 54µsec of Toff, 190A of input current, electrode feed of 3 mm/min with 7 gm of electrode tension, 10V of servo voltage and 2060 mm/min of 10V. Execution of ANOVA on grey grade identifies that, wire tension was the parameter that influences more by 25.89%, followed by Ton and servo voltage by 21.37% and feed rate of wire by 11.89%, with an R2 value of 96.55%. For validating the results, confirmation experiment was also done

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.

PurposeInconel 718 (IN718) is a high-performance nickel-based superalloy with high oxidation-corrosion-temperature resistance, high strength (tensile, fatigue, creep and rupture), durability, toughness, hardness and dimensional stability, which is difficult to machine with traditional fabrication methods. To overcome these difficulties, wire electrical discharge machining (WEDM), one of the modern manufacturing methods, is used.Design/methodology/approachMain performance criteria in WEDM; material removal rate (MRR), cutting speed, surface roughness, cutting width (kerf) and wire wear rate. In this study, the effect of processing parameters on kerf and MRR because of processing IN718 in WEDM was investigated. Machining parameters, voltage, wire feed rate and dielectric fluid pressure were determined. Deionized water was used as a dielectric fluid and 0.3 mm brass wire was used as wire in the experiments. 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 WEDM. Analysis of variance (ANOVA) was used to determine the effect percentages of the cut-off parameters.FindingsThe parameter with the highest effect was determined as tension with a rate of 76.95% for kerf and 91.21% for MRR.Originality/valueThe novel approach uses Taguchi-based GRA optimization as a result of cutting IN718 with WEDM, reducing cost and time consumption.
