Abstract

In order to obtain high quality surfaces in machining, the cutting parameters must be taken into account. Incorrectly selected cutting parameters not only result in rapid wear of the cutting tool but also prevent the surface from being of desired quality. Therefore, it is of great importance to use various experimental design methods to obtain cutting surfaces as defined in the technical drawings with appropriate cutting parameters. In this study, Al 7075 material, which is used in different areas of industry, was processed under dry machining conditions and by milling. Improvement of processing parameters such as cutting speed, feed rate and depth of cut used in machining has been done by creating a three-level Box-Behnken experiment design combined with response surface method. Surface roughness (Ra) values resulting in milling were measured and analyzed. The cutting parameters affecting the surface roughness were optimized. In addition, according to the results of the analysis, it was determined that the feed rate has the greatest effect on the surface roughness in machining.

Özet

Talaşlı imalat sırasında yüksek kaliteli yüzeyler elde etmek için işlem girdisi kesme parametrelerinin dikkatealınması gerekir. Yanlış seçilen kesme parametreleri, hem kesici takımın çabuk aşınmasına yol açmakta hem deyüzeyin istenilen kalitede olmasını engellemektedir. Bundan dolayı, uygun kesme parametreleri ile teknikresimde tanımlanan kalitede yüzeyler elde etmek için çeşitli deneysel tasarım yöntemlerinin kullanılması büyükönem taşımaktadır. Bu çalışmada, sanayinin farklı alanlarında kullanılan Al 7075 malzemesi, kuru işlemeşartlarında ve frezeleme yöntemi ile işlenmiştir. İşleme sırasında kesme hızı, ilerleme hızı ve kesme derinliğigibi işleme parametrelerinin iyileştirilmesi, yanıt yüzey metodu ile kombine edilmiş üç seviyeli Box-Behnkendeney tasarımı oluşturularak yapılmıştır. Frezeleme sonucu oluşan yüzey pürüzlülüğü (Ra) değerleri ölçülerekanaliz edilmiş ve yüzey pürüzlülüğünü etkileyen kesme parametreleri iyileştirilmiştir. Çalışmadan elde edilenbulgulara göre ilerleme hızının yüzey pürüzlülüğü üzerinde en büyük etkiye sahip olan parametre olduğu tespitedilmiştir.
