Kesici Takım Geometrisinin CW511L Kurşunsuz Pirinç Malzemenin İşlenebilirliğine Etkisinin İncelenmesi

Öz

Kurşunsuz pirinç malzemeler çok geniş bir uygulama alanına sahip olmasına rağmen talaşlı işlenebilirliğinde halen problemlerle karşılaşılabilinmektedir. Bu çalışmada kurşunsuz pirinç olan CW511L malzemenin talaşlı işlenebilirliği farklı kesme hızları, takım talaş açısı ve ilerleme değeri bakımından incelenmiştir. Elde edilen bulgular düşük kesme hızında ve ilerleme değerinde kesme kuvvetinin ve kesme sıcaklığının azaldığını göstermektedir. Ayrıca takım geometrisi işlenebilirliği doğrudan etkilemiştir. En yüksek mikrosertlik değeri negatif talaş açısıyla yapılan deneylerde elde edilmiştir. Ayrıca malzemenin deformasyon hızının 105 s-1 olduğu hesaplanmıştır. Deformasyon hızına takım geometrisinin etkisi sınırlı olurken kesme hızının etkisi belirgin farklılıklar sağlamıştır.
