Abstract: In a grinding process, the grinding force is generated from the joint actions of sliding friction, plough and cutting. The calculated grinding force which only takes account of the cutting process has big error, compared with the measured values. Based on the shock effect in the grinding contact area on the grinding process, the contact area was divided into impact area and cutting area. Changes in the impact load from the grits on a workpiece in the impact zone were analyzed to model the impact load generated from single grit, as well as modeling the number of grits involved in the impact. Moreover, the theoretical calculation models of grinding force and total grinding force were also developed. Experimental study verified the correctness of the theoretical analysis.

Key words: surface grinding, contact area, grinding force modeling, impact load
