Abstract

In this study, surface quality and tangential cutting force and radial width (ae) and axial deep (ap) parameters were investigated in the processing of white marble, which is a natural building material. Five different white marbles were used in the experiments and the taguchi method was applied as the test method. Depending on the number and level of parameters, the L9 orthogonal array was chosen. Cutting forces and surface roughness data were collected for each marble. The optimal level and contribution percentage of each parameter was determined by applying the analysis of variance with the signal-to-noise (S/N) ratio. The Fr and Ra factors for all marbles were found to be ae:1 mm and ap:1 mm. Depending on the significance level, axial depth of cut (ap) was the primary effective parameter (65-86% for Fr; 42-78% for Ra), while radial depth of cut was the secondary effective parameter (3-24% for Fr; 16-35% for Ra). It can be said that the feed rate parameter was not an effective parameter in general.As a result of regression analysis, a significant relationship of 83% was observed between Ra surface roughness value and mineral grain size. Grain size has been the mineralogical-petrographic feature affecting the surface quality of marbles.

Özet

Bu çalışmada, doğal bir yapı malzemesi olan beyaz mermerin işlenmesinde yüzey kalitesi ve teğetsel kesme kuvveti ile radyal genişlik (ae) ve eksenel derinlik (ap) parametreleri araştırılmıştır. Deneylerde beş farklı beyaz mermer kullanılmış ve test yöntemi olarak Taguchi yöntemi uygulanmıştır. Parametre sayısı ve seviyesine bağlı olarak L9 ortogonal dizisi seçilmiştir. Her bir mermer için kesme kuvvetleri ve yüzey pürüzlülüğü verileri toplanmıştır. Her bir parametrenin optimum seviyesi ve katkı yüzdesi, sinyal gürültü (S/N) oranı ile varyans analizi uygulanarak belirlenmiştir. Tüm mermerler için Fr ve Ra faktörleri, ae:1 mm ve ap:1 mm olarak bulundu. Anlamlılık seviyesine bağlı olarak, eksenel kesme derinliği (ap) birincil etkin parametre (Fr için 65-86%; Ra için 42-78%), radyal kesme derinliği ikincil etkin parametre (3-24% for Fr; 16-35% for Ra) olmuştur. İlerleme hızı parametresinin ise genel olarak etkin bir parametre olmadı söylenebilir. Regresyon analizi sonucunda Ra yüzey pürüzlülüğü değeri ile mineral tane boyutu arasında %83 oranında anlamlı bir ilişki gözlenmiştir. Tane boyutu, mermerlerin yüzey kalitesini etkileyen mineralojik-petrografik özellik olmuştur.
