A cutting force computational model based on the form-shaping function theory is developed. In the precision machining, small deviations of the geometrical form of the cutting tool and its total run-out can result in significant variation of the instantaneous tool-and-workpiece contact area and depth-of-cut compared to their nominal values. This produces corresponding changes in the instantaneous cutting power and cutting force. As application examples, the surface grinding and precision turning are considered. In the latter case, the machined profile deviations are reduced thanks to the amplitude modulation of the force variations, which depends upon a ratio of rotation to vibration frequencies. The model is verified using the known experimental data.
