Dövme ve Döküm Alüminyum Alaşımlarının İşlenmesinde Takım Aşınması: Literatür Araştırması

Alüminyum ve alaşımları hafiflik, yüksek mukavemet/ağırlık oranı ve kolay şekillendirilebilme özelliklerinden dolayı endüstride yaygın kullanım alanına sahiptir. İstenilen formlarda üretilebilmesi ve mekanik sistemlerde nihai ürün olarak kullanılabilmeleri için tornalama, delme, frezeleme ve diş açma gibi farklı işleme operasyonlarına ihtiyaç duyulmaktadır. Ancak, bu malzemelerin işlenmesi esnasında işlenmiş yüzey kalitesini, boyutsal toleransı ve kesici takım performansını olumsuz etkileyen bazı sorunlar ortaya çıkmaktadır. Kesici takım aşınması, bu sorunlardan en önemlileri arasında yer almaktadır. Kesici takım aşınması, işleme operasyonlarında takım değiştirme ve takım tezgâhı ayarlama gereksinimlerinden dolayı zaman kaybına da yol açmaktadır. Bu çalışmada, literatürde alüminyum esaslı alaşımların işlenmesinde takım aşınması üzerine yapılan güncel çalışmalar detaylı bir şekilde araştırılmış ve takım aşınması üzerinde etkili olan faktörler karşılaştırmalı olarak ortaya konulmuştur.

Anahtar Kelimeler:

Alüminyum alaşımları, İşlenebilirlik, Kesme kuvveti, Yüzey pürüzlülüğü, Takım aşınması

Tool Wear in Machining of Wrought and Cast Aluminium Alloys: Literature Review

Aluminum and its alloys are widely used in industry due to their lightness, high strength/weight ratio and easy formability. Different machining operations such as turning, drilling, milling and threading are needed in order to be manufactured in desired forms and used as a final product in mechanical systems. However, some problems arise that negatively affect the machined surface quality, dimensional tolerance and cutting tool performance during the machining of these materials. Cutting tool wear is among the most important of these problems. Cutting tool wear also causes loss of time due to tool changing and machine tool adjustment requirements in machining operations. In this study, current studies on tool wear in the machining of aluminum-based alloys were investigated in detail and the factors affecting tool wear were presented comparatively.
