Abstract

Hadfield çelikleri yüksek aşınma direncine, tokluğa, yüksek akma ve çekme mukavemetine sahip malzemelerdir. Ray çelikleri olarak da bilinen Hadfield çelikleri aşınma, darbe ve yorulma dayanımından dolayı çoğunlukla demiryolu ulaşımında kullanılmaktadır. Bu çalışmada, Hadfield çeliklerinin işleme davranışı ve işleme parametrelerinin yüzey pürüzlülüğü, makine gürültüsü ve güç tüketimi üzerindeki etkisi kuru işleme koşullarında yatay freze tezgâhı kullanılarak araştırılmıştır. Deneysel çalışmalar, ağır işleme koşullarında sabit kesme hızı, dört farklı ilerleme hızı ve altı farklı talaş derinliğinde ve gerçek bir üretim ortamında yapıldı. Frezeleme değişkenlerinin yüzey pürüzlülüğü, makine gürültüsü ve güç tüketimi üzerindeki etkisi varyans analizi (ANOVA) kullanılarak değerlendirildi. Deneysel sonuçlar, kesme derinliğinin yüzey pürüzlülüğü üzerindeki en önemli kesme parametresi olduğunu göstermiştir. Kesme derinliğinin artmasıyla yüzey pürüzlülüğü değeri belirgin şekilde iyileşmiştir. Güç tüketimi ve makine gürültüsü, deneylerde kullanılan artan ilerleme hızı ve kesme derinliği değerlerinin artmasından etkilenmiştir.

Effect of the Cutting Parameters on Surface Roughness, Power Consumption and Machine Noise in Machining of R260 Steel

Abstract

Hadfield steels are the materials having with high wear resistance, toughness, high yield and tensile strength. Hadfield steels, also known as rail steels, are commonly used for rail transport due to their wear, impact and fatigue strength. In this study, machining behavior of the Hadfield steels and the effect of the machining parameters on surface roughness, machine noise and power consumption were investigated under dry cutting conditions using horizontal milling machine. Experimental studies were carried out a real production environment using constant cutting speed, four different feed rate and six different depth of cut under heavy machining conditions. The influence of the milling variables on surface roughness, machine noise and power consumption were evaluated by using Analysis of variance (ANOVA). The experimental results showed that the depth of cut was the most significant cutting parameter on the surface roughness. Surface roughness value was remarkably improved with increasing depth of cut. Power consumption and machine noise were affected from increasing feed rate and depth of cut values used in the experiments.
