Avrupa demir yolu hatlarında kullanılmakta olan EN13262 standardına göre üretilmiş ER7 kalite çelikleri Kardemir A.Ş Demir Yolu Tekeri Üretim Tesislerinde üretilebilmektedir. Pres ve haddeleme ile üretilen bu tekerlekler üserim prosesinin ardından nihai ölçülerine getirilmek üzere talaşlı imalat sürecine girmektedir. Bu çalışmada MT-TiCN+Al2O3 CVD coated-RCMX 1606M0 K15 kalite takım kullanılarak kuru test koşullarında ER7 tekerlek malzemesinin 1mm kesme derinliği değeri ile tornalanması sırasında ilerleme hızı (FR) ve kesme hızı (CS) parametrelerinin yüzey pürüzlülüğü (SR), güç harcaması (PC) ve kesme sıcaklığı (CT) üzerindeki etkileri araştırılmıştır. Giriş parametrelerinin sonuçlar üzerindeki etki oranlarının tespitinde Analysis of Varyans (ANOVA) yöntemi kullanılmıştır. Ayrıca Response Surface Metodu kullanılarak tahmin denklemleri elde edilmiştir. Bu çalışmanın sonucunda yüzey pürüzlülüğü için etkili parametre %57.158 ile ilerleme hızı olurken, güç harcaması ve kesme sıcaklığı için etkili parametrenin kesme hızı olduğu tespit edilmiş olup sırası ile %58.071 ve %64.797 olarak bulunmuştur.

ER7 quality steels produced according to EN13262 standard used in European railway lines can be produced at Kardemir A.Ş Railway Wheel Production Facilities. These wheels, which are produced by pressing and rolling, are included in the machining process to be brought to their final dimensions after the production process. In this experimental study, the effects of cutting speed (CS) and feed rate (FR) on surface roughness (SR), power consumption (PC) and cutting temperature (CT) were investigated during turning of ER7 wheel material with 1mm depth of cut value under dry test conditions using MT-TiCN+Al2O3 CVD coated-RCMX 1606M0 K15 quality tool. Analysis of Variance (ANOVA) method was used to determine the effect rates of the input parameters on the results. In addition, estimation equations were obtained using the Response Surface Method. As a result of this study, the effective parameter for SR is FR with 57.158%, while the effective parameter for PC and CT is found to be CS, and it is found to be 58.071% and 64.977%, respectively.
