Özet:

 In this study, NPT taper threading was performed on materials with different hardness St37-2S235JR, 11SMnPb37 and C451.0503 and the effects of machining parameters on the main cutting force Fc and rake α were experimentally investigated. Four different cutting speeds 50, 60, 70 and 80 mmin, 1.411 mmrev pitch and two different coated cutting tools ALCrN ALCrSIN, TİALN coated by PVD method were used in the experiments. The depth of cut was taken as constant 1.015 mm in all experiments. Analysis of variance ANOVA was performed to determine the effective parameters on the experimental results and the optimum machining parameters were determined by response surface methodology RSM. According to the ANOVA results, it was found that the material hardness had the greatest effect on Fc and α values. It was concluded that the optimum values will be obtained when 11SMnPb37 material is machined at a cutting speed of 63.6364 mmin using TİALN PVD coated tool.

 Bu çalışmada, farklı sertliğe sahip malzemeler St37-2S235JR, 11SMnPb37 ve C451.0503 üzerine NPT konik diş açma işlemi uygulanmış ve işleme parametrelerinin esas kesme kuvveti Fc ve eğim α üzerine etkileri deneysel olarak araştırılmıştır. Deneylerde dört farklı kesme hızı 50, 60, 70 ve 80 mdak, 1,411 mmdev adım ve PVD yöntemi ile kaplanmış iki farklı kaplamalı kesici takım ALCrN ALCrSİN, TİALN kullanılmıştır. Kesme derinliği ise tüm deneylerde sabit 1,015 mm alınmıştır. Deney sonuçları üzerinde etkin parametrelerin belirlenmesi için varyans analizi ANOVA yapılarak, yanıt yüzeyi metodolojisi RSM yöntemiyle optimum işleme parametreleri tespit edilmiştir. ANOVA sonuçlarına göre Fc ve α değerleri üzerinde en büyük etkiye malzeme sertliğinin sahip olduğu tespit edilmiştir. Optimum değerlerin 11SMnPb37 malzemenin TİALN PVD kaplamalı takım kullanılarak 63,6364 mdak kesme hızında işlendiğinde elde edileceği sonucuna ulaşılmıştır.
