An Experimental Investigation into The Optimal Processing Conditions for The Diamond Paste Polishing of SKD 61 Mold Steel
Bu çalışmada, parlatma süresi, eksenel yükleme ve fener mili hızı gibi elmas macunuyla parlatma parametrelerinin SKD 61 kalıp çeliğinin yüzey pürüzlülüğü ve speküler yansıması üzerindeki etkisi deneysel olarak araştırılmıştır. Deneyler Taguchi ortogonal deneysel tasarım dizisine göre yapılmış olup her bir faktörün istatistiksel önemi ve ölçülen yanıtlar ile optimal parametre seviyeleri üzerindeki etkileşimleri varyans analizi (ANOVA) ve esas etki grafikleri kullanılarak belirlenmiştir. Her bir çıktı karakteristiğini tahmin etmek için doğrusal bir regresyon denklemi geliştirilmiştir. Parlatılan yüzeyler atomik kuvvet mikroskobu (AFM) kullanılarak incelenmiştir. Geliştirilen modeller, yüzey pürüzlülüğü ve speküler yansıma için sırasıyla 0.74 ve 0.85'lik bir R2 ile yanıtları tahmin etmiştir.

An Experimental Investigation into The Optimal Processing Conditions for The Diamond Paste Polishing of SKD 61 Mold Steel
In this study, the effect of diamond paste polishing parameters such as polishing time, axial loading and spindle speed on the surface roughness and specular reflectance of SKD 61 mold steel were experimentally investigated. The experiments were conducted based on the Taguchi orthogonal array. The statistical significance of the each factor and their interactions on the measured responses and optimal parameter level settings were determined using analysis of variance (ANOVA) and main effect plots. In order to predict the each output characteristic, a linear regression equation was developed. Polished surfaces were studied using atomic force microscope (AFM). The developed models predicted the responses with an R2 of 0.74 and 0.85 for surface roughness and specular reflectance, respectively.
