The Effect on the Cemented Carbide Cutting Tool of Austempering Process

Abstract

Austempered ductile irons (ADI) have been developed for an increasing number of the engineering applications such as crankshaft, gears, and other mechanic equipments because of its combination of strength and toughness. Therefore, austempering process has important effects on the mechanical properties of ADI. In this study, we have investigated the effect of austempering process on the cutting tool stresses. The cutting forces (main cutting force, feed force and thrust force) obtained from experimental studies have been applied to rake face, main cutting edge, auxiliary cutting edge on the cutting tool, and then the stresses (von-Mises, shear stress, normal stresses in the X, Y and Z directions) occurred on the cutting tool has been analyzed based on finite element method using ANSYS Workbench commercial software. It is also observed that analytical process of Frocht for the stresses on cutting tool tip. The results obtained show that the austempering process is the significant factor affecting cutting tool stresses.
