Talaşlı imalat, esasen talaş oluşturma ve kırma işlemidir; bu işlem sırasında iş parçasının yüzeyinin temizlenmesi ve daha pürüzsüz ve mekanik olarak uzun ömürlü bir yapı elde etmek için yeni bir yüzey oluşturulması istenir. Talaşlı imalat, her biri belirli bir amaç için uzmanlaşmış birçok işlemi içerir. En önemli işleme işlemlerinden biri tornalamadır. Tornalama, farklı işleme parametrelerine sahip çeşitli takım tezgahları, kesici takımlar ve fikstürler kullanılarak gerçekleştirilir. Bu makale, kesme hızı, ilerleme hızı ve kesici takım üzerindeki kaplama malzemeleri gibi faktörleri dikkate alarak AA7075-T6 alaşımının işlenebilirlik çalışmasına odaklanmaktadır. Bu çalışmada değerlendirilen tepki parametreleri kesme kuvvetleri, kesme sıcaklıkları ve enerji tüketimidir. Bulgulara göre, ilerleme hızı, kesme hızı ve kaplama malzemeleri sırasıyla kesme kuvvetleri, enerji tüketimi ve kesme sıcaklıkları üzerinde baskın parametreler olarak bulunmuştur. Bu makale için geliştirilen çerçeve, popüler ve geçerli işlenebilirlik göstergelerini dikkate alarak modern kaplama malzemelerini karşılaştırarak güncel literatüre katkıda bulunmayı amaçlamaktadır.

The Effects of Coating Materials on Machinability Characteristics of AA7075-T6 Alloys under Different Turning Conditions

Öz

Machining is essentially a process of creating and breaking chips, during which it is desired to clean the surface of the workpiece and create a new surface to obtain a smoother and mechanically long-lasting structure. Machining involves many processes; each specialized for a specific purpose. One of the most important machining processes is turning. Turning is performed using a variety of machine tools with different machining parameters, cutting tools, and fixtures. This paper focuses on the machinability study of AA7075-T6 alloy considering the factors such as cutting speed, feed rate and coating materials on the cutting tool. The response parameters evaluated in this study is the cutting forces, cutting temperatures, energy consumption. According to the findings, feed rate, cutting speed and coating materials were found as the dominant parameters on cutting forces, energy consumption and cutting temperatures respectively. This situation is seen in the ANOVA tables that feed is the most effective parameter for cutting force with 33.05%, coating is the most effective parameter for temperature with 3.45% and cutting speed is the most effective parameter for energy consumption with 45.54%. The frame developed for this paper aims to contribute to the current literature by comparing modern coating materials considering popular and valid machinability indicators.
