Abstract

In this study, the effects of cutting speed; over the formation of Built-Up Layer (BUL) and Built-Up Edge (BUE) were investigated. For this purpose, AA5052 alloy was processed on a Computer Numeric Control (CNC) lathe with uncoated cemented carbide insert in dry conditions. As processing parameters in the experiments, five different cutting speeds (100, 200, 300, 400, 500 m/min), constant feed rate (0,30 mm/rev) and connstant depth of cut (1,5 mm) were selected. As the result of the experiments, it was stated that BUL and BUE were formed on cutting tool mostly in machining at 100 m/min cutting speed and 0,30 mm/rev feed rate. Increasing the cutting speed decreased BUL and BUE formation but they could not be stopped in the tested range.

Özet

Bu çalışmada, işleme parametrelerinden kesme hızının Yığıntı Katmanı (Built-Up layer) (YK) ve Yığıntı Talaş (Built-Up Edge) (YT) oluşumu üzerindeki etkileri araştırılmıştır. Bu amaçla, AA5052 alaşımı; kaplamasız karbür takımla bilgisayarlı sayısal denetimli (BSD) torna tezgahında, kuru olarak işlenmiştir. Deneylerde, beş farklı kesme hızı (100, 200, 300, 400, 500 m/min), sabit ilerleme hızı (0,30 mm/dev) ve sabit kesme derinliği (1.5 mm) işleme parametreleri olarak seçilmiştir. Talaş kaldırma işlemleri sonucunda, kesici takım üzerinde en fazla YK ve YT, 100 m/min kesme hızı ve 0,30 mm/dev ilerleme hızında yapılan talaş kaldırma işleminde oluştuğu tespit edilmiştir. Kesme hızının artırılması YK ve YT oluşumunu azaltmış, fakat denenen sınırlar içerisinde YK ve YT oluşumu engellenememiştir.
