Due to its high strength, turning of tibial component made from CoCrMo
material used in knee prostheses is faced with high cutting forces, pinking,
vibration and tool wear. This situation both manufacturing cost and
manufacturing time. In this study, the effects of surface roughness, vibration,
surface defects and micro hardness on the number of revolutions and progress of
turning of CoCrMo material with carbide cutting tool were investigated. As a
result of the experiments, it has been found that surface roughness and defects
increase due to the increase of the progress, and the roughness decreases due
to the increase of the number of revolutions. In addition, CoCrMo alloy was
analyzed by machining with finite element processing temperature distributions
were also determined during turning.

Yüksek
dayanımından dolayı diz protezlerinde kullanılan CoCrMo malzemesinden yapılmış
tibial bileşenin tornalanmasında büyük kesme kuvvetleri, vuruntu, titreşim ve
takım aşınması gibi olumsuzluklarla karşılaşılmaktadır. Bu durum hem imalat
maliyetini hem de imalat süresini artırmaktadır. Bu çalışmada, CoCrMo malzemesinin
karbür kesici takım ile alın tornalanmasında devir sayısının ve ilerlemenin
yüzey pürüzlülüğüne, yüzey defektlerine ve mikro sertliğe etkileri
araştırılmıştır. Deneyler sonucunda ilerlemenin artmasına bağlı olarak yüzey
pürüzlülüğü ve defektlerin arttığı, devir sayısının artmasına bağlı olarak ise
pürüzlülüğün azaldığı tespit edilmiştir. Ayrıca CoCrMo alaşımının sonlu
elamanlarla işleme analizi yapılarak tornalama boyunca sıcaklık dağılımları da
tespit edilmiştir.
