A model is presented which predicts the chip flow direction for nose radius tools with inclination angles. Experimental verification was made in turning that cut on the bars. A comparison of the predicted and experimental results shows excellent agreement, and the results are consistent with previous findings of other workers. The usefulness of the present model is its capacity to predict the chip flow for a given general tool used with any combination of cutting conditions, without any prior knowledge of the work material properties or any machining tests required to determine an empirical formula.
