NC 가공을 위한 공구 선정에 관한 연구

In cutting conditions machine tool, cutting tool and workpiece are most significant factors. Of the conditions, selection of cutting tool is related with machining technology. Semi-finish cutting removes uncut material for finish cutting not to clear large cusp after rough cutting. In spite of this advantage the cutting method is not used in field environments, since the tool selection needs machining experience. Manufacturing field uses rough cutting and finish cutting to produce parts without supporting the need in current manufacturing. The paper looks into appropriate diameter of cutting tool in rough. semi-finish, finish cutting for each objectives. Tool dimension is selected on cutting force and cutting speed in the rough cutting. on deflection of cutting tool and accuracy of surface in finish and on uncut removal in semi-finish. For semi-finish cutting the uncut after rough cutting, rough cutting can elevate efficiency of cutting and finish cutting accuracy of surface without cutting force considered.
