Tornalama Sonrası Çıkan Talaşlardan Elde Edilen Alüminyum 5000 Alaşımının Yüzey Pürüzlülüğünün Taguchi Yöntemi ile Analizi

Artan üretim talepleri doğal kaynakların aşırı tüketilmesine neden olmaktadır. Bu aşırı tüketimin önüne geçebilmek için malzemelerde geri dönüşümün önemi artmaktadır. Bu çalışmada, kullanım alanı her geçen gün artan alüminyum 5000 alaşımı tornalanmıştır. Tornalama sonrası çıkan talaşlar döküm yöntemi ile geri dönüştürülmüştür. Elde edilen yeni üründe de tornalama işlemi yapılmıştır. İlk tornalama ve son tornalama işleminde ortaya çıkan yüzey pürüzlülük değerleri incelenmiştir. Deneyler Taguchi yöntemi ile tasarlanmış ve yine sonuçlar da Taguchi yöntemi ile analiz edilmiştir. Kesme parametreleri olarak kesme hızı, ilerleme oranı ve kesme derinliği seçilmiştir. Deneyler bu üç parametrenin üç seviyesi ile Taguchi L9 deney düzeneği kullanılarak yapılmıştır. Döküm malzeme normal malzemeden daha sert çıkmıştır. Hem normal hem de döküm malzemede en düşük yüzey pürüzlülüğü 1. deneyde çıkmıştır. (Kesme hızı 200 m/dk, ilerleme oranı 0.1 mm/dev ve kesme derinliği 0.2 mm). Her iki malzemenin tornalanmasında en etkin parametre ilerleme oranı olmuştur.

Analysis of Surface Roughness of Aluminum 5000 Alloys Obtained from Chips After Turning by Taguchi Method

Increasing production demands cause excessive consumption of natural resources. In order to prevent this excessive consumption, the importance of recycling in materials is increasing. In this study, aluminum 5000 alloys whose usage area is increasing day by day have been turned. The chips after turning have been recycled by the casting method. Turning process was also performed in the new product obtained. The surface roughness values that appeared during the first turning and the final turning were examined. The experiments were designed by Taguchi method and again the results were analyzed by Taguchi method. Cutting speed, feed rate and cutting depth were chosen as cutting parameters. Experiments were carried out using the Taguchi L9 experiment setup with three levels of these three parameters. The cast material was harder than nominal material. The lowest surface roughness was found in the 1st experiment for both normal and cast materials. (Cutting speed 200 m/min, feed rate 0.1 mm/rev and cutting depth 0.2 mm). The most effective parameter in turning of both materials was the feed rate.
