Abstract (2. Language): 
In this study, a standart ferrous powder metallurgy (PM) copper steels were produced as copper ratio gradually was increased between the range of 1-4 % while other PM process parameters were kept constant. Machinability tests were carried out with drilling process on these samples. In machinability tests have been measured thrust forces, tool wears and surface roughness of the hole surface and taken optical photos from generated chips during machining of each materials group. Thus, effect of increasing copper ratio on tool wear and relation with chip formation which results from machining PM materials was experimentally investigated. The results showed that tool wear decreased and chip formation improved with increasing copper ratio. This results are also supported by the data obtained from cutting force and surface roughness
Abstract (Original Language): 
Bu çalışmada standart bir demir-esaslı Toz Metal (TM) bakır çeliğinin (FC-0208) diğer TM proses parametreleri sabit tutularak, içerisindeki bakır oranı % 1-4 arasında 4 farklı kademede artırılarak üretimi yapılmış ve bu numuneler üzerinde delik delme talaşlı imalat testleri gerçekleştirilmiştir. Yapılan testlerde her bir malzeme grubunun işlenmesi esnasında oluşan itme-ilerleme kuvveti, takım aşınması ve deliklerin yüzey pürüzlülüğü ölçülmüş, ayrıca talaş morfolojisini incelemek için optik fotoğrafları çekilmiştir. Çalışmanın amacı; artan bakır oranının, TM tekniğiyle üretilen bu malzemelerin talaşlı işleme sonucu oluşan takım aşınması ve onunla ilişkili talaş oluşumuna etkisini deneysel olarak araştırmaktır. Sonuçlar, artan bakır oranının takım aşınmasını azalttığı, talaş oluşumunu iyileştirdiğini göstermiştir. Elde edilen kesme kuvveti ve yüzey pürüzlülüğü verileri de bunu destekler niteliktedir.
