A method is presented for identifying the chip formation, plowing, and sliding forces in turning from force transients. For this purpose, a simple model is used which separates the cutting force into a sharp tool chip formation component and a residual component associated with both rubbing between the wear land and the workpiece and plowing at the cutting edge. Variations of the cross-sectional area of the cut during a transient are used to tune the model and estimate its parameters.
