AISI 1040 çeliğinin tornalanması sonucu oluşan yüzey pürüzlülük değerlerinin RSM ve YSA ile araştırılması

Öz Bu çalışmada, Design Expert programında yüzey yanıt metodu (RSM) Box-Behnken tasarımına göre deney listesi oluşturulmuştur. Oluşturulan deney listesine uygun olarak AISI 1040 çeliğinin tornalaması sonucu yüzey pürüzlülük değerleri elde edilmiştir. Elde edilen yüzey pürüzlülük değerleri ile RSM modeli ve yapay sinir ağı (YSA) modeli oluşturulmuştur. RSM modeli ile ikinci dereceden regresyon denklemi, varyans analizi (ANOVA) parametre etkileşimlerinin yüzey pürüzlülüğüne etkisi iki boyutlu kontur grafiği ve üç boyutlu yanıt grafiği, optimum kesme parametreleri incelenmiştir. Matlab R2013a programı ile YSA modeli oluşturulmuştur. RSM ve YSA modellerinin tahmin sonuçlarının doğruluğunu araştırmak için üç tane test deneyi belirlenmiştir. Test deneyleri gerçekleştirilmiştir. Daha sonra deneysel Ra, RSM tahmini Ra ve YSA tahmini Ra değerleri kıyaslanmıştır. Bu kıyaslama sonucu RSM modelinin yaklaşık %90 doğrulukla test sonucunu tahmin ettiği belirlenmiştir.
