<p><P>PROBLEM TO BE SOLVED: To easily measure the clearance between a cutting punch and a die in a cutting machine constituted of the cutting punch and the die. <P>SOLUTION: A cutting machine 100 includes the dies (106a and 106b), and the cutting punch 310 having a blade on at least a surface opposing to the die, and the cutting punch 310 is brought close to the die to cut a workpiece. In the cutting machine 100, the cutting punch 310 is provided with local slopes (316 and 318) which are expanded at the predetermined angle in a direction away from the die side to allow the light transmitted through a clearance between the cutting punch and the die and reflected by the local slope to be observed. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
