In the first part of this investigation a model of oblique cutting, in which boundary of the chip and workpiece in the plane normal to the cutting edge is constructed by two circular arcs and the condition of up-curl of the chip is satisfied, was developed. The cutting model enables to predict the chip formation and the cutting forces by specifying the tool-chip contact length and frictional condition on the tool face. In this paper three components of the cutting force and the chip formation such as chip flow angle, normal shear angle and radius of up-curl of the chip are measured and compared with those predictions. Most of the predicted results agree well with the measured results. On the radius of up-curl of the chip predicted and measured values are in good agreement in the range of large inclination angles.
