Abstract

This paper investigates the accuracy of using the Woxén equivalent chip thickness to represent feed, depth of cut, nose radius and major cutting angle in tool life modeling of machining low alloy steel in longitudinal turning. Hägglund’s way of calculating the equivalent chip thickness has been used and compared to the Woxén equation. The equivalent chip thickness was held constant as the tool life was recorded for varied feeds and depths of cut. The results show that the tool life decreases for an increase of depth of cut and a decrease of feed, using the same equivalent chip thickness.
