Abstract

While cutting tools deformed during machining inevitably, it is highly important to monitor the developing wear in terms of determining the cutting performance of cutting tool. Due to non-uniform wear distribution on the cutting tool, determination of location and extent of the wear is required. Crater wear occurred on the rake face of the cutting tool with the effect of abrasive, adhesive and diffusion mechanisms, a tool wear type leads to tool failure in case of excessive progress. The study carried out to investigate the relationship between tool rake face temperature and crater wear during turning of AISI 5140, being as the first in the field. In the context of the study, cutting speed, feed rate, depth of cut and cutting edge angle parameters were used, experiments were carried out under dry cutting conditions. Crater wear was measured from cutting tool when the turning operation stopped however tool temperature was monitored as online with the assistance of temperature sensor. Statistical and graphical results demonstrated that cutting speed is the most effective parameter on crater wear (71.3%) and tool temperature (78.5%). Since the cutting speed have impact on the friction conditions along the rake face of cutting tool and being influential factor on abrasive and diffusion wear mechanisms, it is concurred that a strong relationship between tool temperature and crater wear exist.

Tornalama Parametrelerinin Kesme Sıcaklığı ve Krater Aşınması Üzerine Etkilerinin Deneysel Olarak Araştırılması

Abstract

Kesici takımlar işleme esnasında kaçınılmaz olarak deforme olurken, meydana gelen aşınmayı takip etmek takımın işleme performansını tayin etmek açısından son derece önemlidir. Takım yüzeylerinde aşınmanın düzenli bir yapıda yayılmaması, aşınmanın yeri ve miktarının belirlenmesini gerektirmektedir. Krater aşınması aşındırıcı, yapışma ve difüzyon aşınması mekanizmalarının etkisi ile kesici takımın talaş yüzeyinde meydana gelen, fazla ilerlemesi durumunda takım kaybına yol açabilen bir takım aşınması tipidir. Bu çalışma, AISI 5140 malzemenin tornalanması esnasında kesici takımda meydana gelen krater aşınmasının takım talaş yüzeyi sıcaklığı ile ilişkisinin incelenmesi amacı ile yapılmış olup, bu alanda bir ilk niteliğindedir. Çalışma kapsamında kesme hızı, ilerleme, talaş derinliği ve yaklaşma açısı parametreleri kullanılmış olup deneyler kuru kesme şartlarında gerçekleştirilmiştir. Krater aşınması tornalama işlemi durdurulduğunda kesici takım üzerinden ölçülmüş, takım sıcaklığı ise sıcaklık sensörü yardımı ile anlık olarak izlenmiştir. İstatistiksel ve grafiksel sonuçlar, kesme hızının krater aşınması (71.3%) ve takım sıcaklığı (78.5%) üzerinde en etkili parametre olduğunu ortaya koymuştur. Tornalamada kesme hızının talaş yüzeyinde kesici takım ve iş parçası sürtünme koşulları üzerinde etkili olması ve bu bölgede meydana gelen aşındırıcı ve difüzyon aşınma mekanizmalarını tayin etmesi sebebiyle krater aşınması ve takım sıcaklığı arasında kuvvetli bir ilişki olduğu düşünülmektedir.
