AB  - Bu çalışmada, östemperlemeişleminin kesici takım gerilmeleri üzerindeki etkisi incelenmiştir. Deneyselçalışmalardan elde edilen kesme kuvvetleri (esas kesme kuvveti, ilerleme kesmekuvveti ve pasif kuvvet) ANSYS Workbench programında, kesici takımdaki, talaşyüzeyi, esas kesici kenar ve yardımcı kesici kenar üzerine 3 boyutlu olarakuygulanmıştır. Östemperleme sürecinin rolünü vurgulamak için, ilk olarakKüresel Grafitli Dökme Demir (KGDD) numuneler 900°C de 60 dakika tuz banyosundaöstenitlenmiş, daha sonra 60 dakika boyunca 250°C ve 325°C deki bir tuzbanyosunda ısıl işlem yapılmıştır. Analizler sonunda, kesici takım üzerindekieş değer gerilme (vonMises), kayma gerilmesi (Tresca), X, Y ve Z yönlerindekinormal gerilmeler heaplanmıştır.

N2  - In this study, we were investigatedthe effect of austempering process on the cutting tool stresses. The cuttingforces obtained from experimental studies (main cutting force, feed force andpassive force) were applied to rake face, main cutting edge, auxiliary cuttingedge on the cutting tool as three dimensional in the ANSYS Workbench program.To emphasize the role of the austempering process, Ductile Iron (DI) specimenswere firstly austenitized in salt bath at 900°C for 60 min, after which theywere quenched in a salt bath at 250°C and 325°C for 60 min. The equivalentstress (von-Mises), shear stress (Tresca), normal stresses in the X, Y and Zdirections on the cutting tool were calculated at the end of the analysis.
