摘要：
Ploughing force is a parasitic force induced by the blunt cutting edge and the contact at flank face. Investigation on the ploughing force is necessary for the cutting mechanism understanding, the tool wear monitoring, and the tool sharpness evaluation. In this paper, a new comparison method to determine the ploughing force is developed by considering the cutting edge radius. This method is verified in the FEM simulation. Cutting experiments are performed to investigate the ploughing force in microcutting. Not only the cutting edge radius but also the uncut chip thickness is found to have great effects on the ploughing force. The nonlinear increase of the total specific cutting energy is also attributed to the ploughing force.
