切削部Ｅが生ずる。In the printed wiring board, it may be necessary to cut the substrate to form an inward right-angled portion. In order to form the right angle portion, it is machined as shown in FIGS. 1 (a) to (c). That is, the printed wiring board A is cut by moving the roll-shaped cutting tool D along the two sides C forming the portion B where the right angle portion of the printed wiring board A should be formed. However, according to this method, the cutting tool is roll-shaped and cannot cut the intersection point of both sides at a right angle, and it corresponds to the 1/4 circle of the roll-shaped cutting tool formed on both sides near the intersection and in the vicinity. An uncut portion E surrounded by the curved surface is produced.
