According to the critical size ratio for the characteristic particle size to film thickness between grinding wheel and workpiece, the machining mechanisms in abrasive jet precision finishing with grinding wheel as restraint of advanced engineering ceramic can be categorized into three states, namely, two-body lapping, three-body polishing, abrasive flow jet machining. The critical condition of two-body lapping to three-body polishing transition was analyzed. The single particle material removal modes of two-body lapping, three-body polishing, abrasive flow jet machining were proposed. Experiments were conduced in the refitted surface grinder for academic modes verification. It was found that experimental results were agreement with theoretical modes and the modes validity were verified.
