This paper presents experimental analyses of dynamic expansion pressure of honing stone during internal honing, based on the measurements of expansion force acting to the workpiece. In the cutting state with continuous self-dressing of honing stones, the dynamic expansion pressure coincides with the estimated value which is obtained from a kinetic equation without friction loss. In the glassy state with loading or grazing of the honing stones, the dynamic expansion pressure deviates higher or lower from that of estimation mentioned above. It is considered that the higher value is caused by the wedge action of the stone holder between the taper-cone and workpiece due to the thrust component of the honing force. The dynamic expansion pressure and its change are correlated with the honing farces measured in the experiment. Honing force, which is one of the main factors affecting the heat generation, is influenced by the expansion character of honing stone, cutting character of the stone and dynamic expansion pressure.
