Abstract
In this study, we were investigated the effect of austempering process on the cutting tool stresses. The cutting forces obtained from experimental studies (main cutting force, feed force and passive force) were applied to rake face, main cutting edge, auxiliary cutting edge on the cutting tool as three dimensional in the ANSYS Workbench program. To emphasize the role of the austempering process, Ductile Iron (DI) specimens were firstly austenitized in salt bath at 900 degrees C for 60 min, after which they were quenched in a salt bath at 250 degrees C and 325 degrees C for 60 min. The equivalent stress (von-Mises), shear stress (Tresca), normal stresses in the X, Y and Z directions on the cutting tool were calculated at the end of the analysis.
