Numerous researches are
being carried out for machining to meet the growing technology and increasing demand.
A significant part of them has been the examination of the relationship between
cutting parameters and surface roughness, tool wear and cutting forces. In
recent years, researches are explained that vibrations, sound level and current
value of the machine have been related to tool wear, surface roughness and cutting
forces. With more economical and easy to use measurements, the machining
process is more understandable and controllable. In this study, the
relationship between CuZn39Pb3material in
the CNC lathe machine, under the dry cutting conditions, 4 different feed rate,
5 different depth of cuts and 4 different cutting speeds effect on sound level,
vibration, current value and surface roughness values. Analysed by RSM (Response
Surface Methodology). Optimum cutting parameters are determined. As the increased
of feed rate, surface roughness, Sound level, vibration and current value of
the machine increased. Vibration value residue, surface roughness value and
sound level increased. It was investigated that there is a strong
correlation between the increase of the machine current value and the sound
level

Gelişen teknoloji ve artan talep
miktarını karşılamak üzere talaşlı imalata yönelik birçok araştırma
yapılmaktadır. Bunların önemli bir kısmı kesme parametreleri ile yüzey
pürüzlülüğü, takım aşınması ve kesme kuvvetlerinin ilişkisinin incelenmesi
şeklinde olmuştur. Son yıllarda yapılan çalışmalarda titreşim, ses şiddeti ve
tezgâhın çektiği akım değeri ile takım aşınması, yüzey pürüzlülüğü ve kesme
kuvvetleri arasında ilişki kurulmuştur. Daha ekonomik ve alınması kolay
ölçümler ile talaşlı imalat süreci daha anlaşılır ve kontrol edilebilir bir
seviyeye gelmektedir. Bu çalışmada CNC torna tezgâhında, kuru kesme
şartlarında, CuZn39Pb3 malzeme, 4 farklı ilerleme, 5 faklı talaş derinliği ve 4
farklı kesme hızında oluşan ses şiddeti, titreşim, tezgâhın çektiği akım değeri
ve yüzey pürüzlülük değerleri arasındaki ilişki incelenmiştir. RSM (Response Surface
Methodology) ile analiz edilmiştir. Optimum kesme parametreleri belirlenmiştir.
İlerleme miktarı arttıkça yüzey pürüzlülük, ses şiddeti, titreşim ve tezgâhın
çektiği akım değerinin arttığı görülmüştür. Titreşim değeri arttıkça, yüzey
pürüzlülük değerinin ve ses şiddetinin artığı görülmüştür. Tezgâh akım
değerinin artması ile ses şiddetinin arasında güçlü bir ilişki olduğu
incelenmiştir.
