The formed tool is used to machine the geometrical shape of bearing rubber seal efficiently. The bearing rubber seal has complex geometry for the complicated geometrical shape to prevent leakage of lubricant oil and influx of the dust effectively. Because it is difficult to machine the unique shape exactly by the conventional tool, the formed tool is used in machining a rubber seal die. In this paper, It is performed to investigate machining characteristic of the formed tool; cutting edge wear, cutting force, and surface quality. Also, an efficient precision machining condition is proposed, and the inspection results of rubber seal with CAl are discussed.

This paper presents the formed tool to machine a milli-structure mold. The formed tool is used to machine the geometrical shape of bearing rubber seal for precision machining. The bearing rubber seal has milli-sized complex geometry. Because it is difficult to machine the unique shape exactly by the conventional tool, the formed tool is used in machining die of the bearing seal. In this paper, it is performed to investigate properties of the formed tool; tool wear, cutting force and machined surface roughness. Tool wear increases rapidly with clearance angle Increase. Thus, the dimension accuracy is affected by the clearance angle.
