CNC TORNA TEZGAHINDA AISI 304 ÇELİKLERİN İŞLENEMESİNDE OPTİMUM YÜZEY PÜRÜZLÜLÜĞÜNÜ SAĞLAYACAK KESME PARAMETRELERİNİN TESPİTİ

Year 2008, Issue: 016, 97 - 104, 15.09.2008

Abstract

The purpose of this study, is to determine optimum machinability parametres required to obtain ideal surface roughness for AISI 304 austenitic stainless steel processed on the CNC lathe. Changes made in the composition of stainless steels so as to provide the mechanical and chemical properties desired according to the fields of application affect also their machining. Surface quality changes according to the machinability. Thirty test specimens, of AISI 304 steel, with a diameter of 61 mm and 250 mm length were prepared and machined in CNC lathes with different cutting conditions. Then, surface roughness was measured using o with printing capability Mahr M1 type desktop perthometer which is a roughness measurement equipment and the results were evaluated for various cutting speed, feed rate and depth of cut. It was found that, increasing the cutting speed yields better surface quality and increasing the feed rate causes an increase in the surface roughness.

CNC TORNA TEZGAHINDA AISI 304 ÇELİKLERİN İŞLENEMESİNDE OPTİMUM YÜZEY PÜRÜZLÜLÜĞÜNÜ SAĞLAYACAK KESME PARAMETRELERİNİN TESPİTİ

Abstract

Bu çalışmada, AISI 304 Östenitik paslanmaz çeliğin CNC torna tezgahında işlenmesi sırasında en ideal yüzey pürüzlülüğünün elde edilebilmesi için optimum işleme parametrelerinin belirlenmesi hedeflenmiştir. Kullanım alanlarına göre istenen mekanik ve kimyasal özelliklerin sağlanması için paslanmaz çeliklerin bileşimlerinde yapılan değişiklikler, paslanmaz çeliklerin işlenebilirliğini etkilemektedir. İşlenebilirliğe bağlı olarak da yüzey kalitesi değişmektedir. Deneyler CNC torna tezgahında, 61 mm çapında ve 250 mm boyunda hazırlanan 30 adet deney numunesi üzerinde değişik kesme parametreleri uygulanarak yapılmıştır. Daha sonra deney numunelerin yüzey pürüzlülükleri, “Mahr” marka perthometer M1 tipi, masa üstü, yazılı çıktı verebilen pürüzlülük ölçüm cihazı kullanılarak ölçülmüş ve pürüzlülüğün, kesme hızı, ilerleme ve talaş derinliğine göre değişimi değerlendirilmiştir. Yapılan çalışmaya göre kesme hızı artırıldığında yüzey pürüzlülüğünün iyileştiği, ilerlemenin artırılması ile yüzey pürüzlülüğünün kötüleştiği görülmüştür.
