Abstract

Strenx 1100 yapısal çeliği, deniz araçları ve ağır araçlar gibi önemli mühendislik uygulamalarında kullanılmasına olanak sağlayan benzersiz malzeme özelliklerine sahiptir. Bu malzemeden üretilen parçaların yüzey bütünlüğü büyük önem taşıdığından, takım aşınma durumunun da dikkate alınması gerekir. Uygulanabilir ve kolay ölçülebildiği için, takım serbest yüzey aşınması (VB) bu alanda yaygın olarak tercih edilir ve kalan takım ömrünü yansıtır. İşlenebilirlik özelliklerini iyileştirmek adına özellikle kesilmesi zor malzemeler için son zamanlarda işleme operasyonlarında minimum miktarda yağlama (MQL) uygulanmaktadır. Bu çalışma Strenx 1100 çeliğinin MMY destekli frezelemesi sırasında serbest yüzey aşınması analizini ve deneylerini içerir. Kesme hızı, ilerleme ve talaş derinliği deneysel plana dâhil edilmiş ve Taguchi L9 tasarımı benimsenmiştir. Ölçülen aşınma sonuçları 3 boyutlu yüzey grafikleri ile değerlendirilmiş, varyans analizi (ANOVA) ve parametrelerin optimizasyonu sinyal / gürültü (S / N) oranına bağlı olarak gerçekleştirilmiştir. Buna göre, kesme hızı serbest yüzey aşınmasını yaklaşık% 53.2 oranında etkileyen ilk parametredir ve bunu yaklaşık % 35.77 ile ilerleme izlemektedir. S / N oranına bağlı parametrik optimizasyon, minimum serbest yüzey aşınması için kesm parametrelerinin birinci sırasının seçilmesi gerektiğini göstermektedir. Bu kapsamlı analiz, çok çeşitli kesme parametrelerinin uygulanması sırasında sınırlamaları ortaya koyduğu için endüstrideki pratik uygulamalar için bir kılavuz niteliğindedir.

Tool Flank Wear Analysis for MQL Assisted Milling of Strenx 1100 Structural Steel

Abstract

Strenx 1100 structural steel has unique material properties enables to utilize in important engineering applications such as marine and heavy vehicles. Due to the surface integrity of the parts produced by this material is of paramount importance, tool wear condition needs to be considered as well. As being applicable and easy to measure, tool flank wear (VB) is widely preferred in the field and reflects the remaining tool life. Minimum quantity lubrication (MQL) has been preferred most recently in machining operations especially for the hard-to-cut materials to improve the machinability characteristics. This paper contains experiments and further analysis of tool flank wear during MQL assisted milling of the Strenx 1100 steel. Cutting speed, feed rate and depth of cut were included in the experimental plan and Taguchi L9 design was adopted. Measured wear results were evaluated with 3d surface plots, analysis of variance (ANOVA) and optimization of parameters were carried out depend on signal to noise (S/N) ratio. Accordingly, cutting speed is the first parameter affecting tool flank wear about 53.2% and followed by feed rate about 35.77%. Parametric optimization depend on S/N ratio shows that first order of theall cutting parameters need to be selected for minimum tool flank wear which is observed on 3d graphs that the increase in the amount of wear with higher parameter levels. This comprehensive analysis is a guide for the practical applications in the industry as providing the limitations during applying a wide range of cutting parameters.
