Abstract

This paper describes the frictional property in conducting the micro texture on the sliding surface for the purpose of improving the tribology property of slideway in machine tool. The numerical calculation that compared tribology properties on several kinds textured surface and smooth surface was carried out. We clarified the effectiveness of dimpled surface to reduce the change of the frictional force. The phenomenon is based on the existence of the local peak of the pressure distribution, which arises in the dimple area. The experiments by the apparatus of the practical size were also carried out in order to verify the calculation result.
