Abstract

Bu çalışmada, birleştirilmiş kesme mekaniği yaklaşımı ve dik talaş kaldırma sürecinin Lagrangian sınırlarına sahip sonlu eleman (SE) modeliyle küresel uçlu parmak frezeleme kuvvetleri araştırılmıştır. Bu kestirimci yaklaşımı kullanarak frezeleme kuvvetlerini belirlemek için dik talaş kaldırma işleminin iki boyutlu SE modeli hazırlanmıştır. Tungsten karbür takımla 20NiCrMo5 çeliğinin işlenmesinde dik talaş kaldırma çıktılarını tespit etmek için tam çiftlenmiş ısıl-gerilme benzetimleri gerçekleştirilmiştir. Dik talaş kaldırma çıktıları, eğik kesme teorisi uygulanarak helisel kesici takım geometrisine taşınmıştır. Sayısal ve analitik çözümlere dayanarak kesme koşullarının bir aralığı için frezeleme kuvvetleri belirlenmiştir.

Keywords
