ABSTRACT Bu çalışmada yüksek ticari saflıkta (%99,8) alüminyum ve çinko elementleri kullanılarak bir adet ikili Al-35Zn
alaşımı üretildi. Alaşım elementlerinin ergitilmesinde orta frekanslı bir indüksiyon ocağı kullanıldı. Ergimiş durumdaki sıvı metal oda
sıcaklığındaki bir kokil kalıpta katılaştırıldı. Üretilen alaşımın frezeleme işlemindeki işlenebilirliği üzerinde farklı kesme hızı
ve ilerleme değerlerinin etkisi deneysel olarak incelendi. Deneyler, 1,5 mm sabit kesme derinliği, üç farklı kesme (600-1200-
1800 dev/dak) ve ilerleme hızı (0,05-0,1-0,15 mm/diş) kullanılarak 6 mm çapa sahip kaplamasız ve TiAlN kaplamalı parmak
frezeler ile gerçekleştirildi. İşlenebilirlik kriterleri olarak kesme deneyleri sonucunda ölçülen kesme kuvveti ve yüzey
pürüzlülüğü değerleri dikkate alındı. Ayrıca, kesme esnasında kesici takımlarda oluşan aşınma, SEM (Scanning Electron
Microscope) ile görüntülenerek gerekli irdelemeler yapıldı. Her iki kesici takım ile yapılan deneyler sonucunda kesme hızının
artması ile kesme kuvveti ve yüzey pürüzlülüğünün azaldığı gözlenirken, ilerlemenin artması ile kesme kuvveti ve yüzey
pürüzlülüğünün arttığı tespit edildi. Kesme kuvveti ve işleme sonucunda elde edilen yüzeyin kalitesi bakımından kaplamasız
karbür kesici takımların Al-35Zn alaşımının frezelenmesinde daha iyi performans gösterdiği görüldü. Deneylerden elde edilen
sonuçlar alaşımın yapısal özelliklerine dayandırılarak irdelendi.
