Punches and dies employed in sheet metal “V” bending have been obtained generally from stock materials, AISI 4140 and EN C45 (Ck 45), in industrial applications through machining. The fact that local and different manufacturing methods have been applied in manufacturing these punches and dies has gained great significance in terms of external dependency and economy. The purpose of this study is to manufacture punches and dies used in “V” bending process from manganese steel via cast method and compare the newly obtained molds with presently used molds in terms of machinability and surface roughness. In this study, the experimental samples from both AISI 4140 and manganese steel were machined at different cutting parameters (cutting speed, feed rate, cutting depth), hence they were compared by analyzing with regard to chip morphology, cutting tool edge wear and surface roughness. At the end of the study, it was concluded that the punches and dies manufactured from manganese steel produced in foundry and widely found are alternatives compared to available AISI 4140 steel molds in terms of machinability.

Döküm Yöntemi ile Manganlı Çelik Malzemeden Üretilen Abkant Pres Zımba ve Dişi Kalıpların İşlenebilirlik Yönünden İncelenmesi

Öz

Sac metal bükmede kullanılan zımba ve dişi kalıplar endüstriyel uygulamalarda genellikle AISI 4140 ve EN C45 (Ck 45) kütük malzemelerden talaşlı imalat yöntemiyle elde edilmektedir. Bu kalıpların imalatında yerel ve farklı imalat yöntemlerinin uygulanması dışa bağımlılık ve ekonomiklik anlamında önem kazanmaktadır. Bu çalışmada amaç, döküm yöntemiyle manganlı çelikten “V” bükmede kullanılan zımba ve dişi kalıplarının imal edilerek elde edilen yeni kalıpların mevcut kalıplarla işlenebilirlik ve yüzey pürüzlülüğü yönüyle karşılaştırılmasıdır. Çalışmada hem AISI 4140 hem de manganlı çelikten deney numuneleri farklı kesme parametrelerinde (kesme hızı, ilerleme, talaş derinliği) işlenerek, talaş morfolojisi, kesici takım uç aşınması ve yüzey pürüzlülüğü yönünden analiz edilerek mukayese edilmiştir. Çalışma sonunda yerelde bulunan dökümhanelerde üretilebilen ve yaygın olarak bulunabilen manganlı çelikten üretilen zımba ve dişi kalıpların mevcut AISI4140 çelikten talaşlı imalat yöntemiyle üretilen kalıplara göre işlenebilirlik yönünden de alternatif olduğu sonucuna varılmıştır.
