Abstract

PURPOSE:To confirm the condition of forming of holes, by providing a step of forming unusable holes with the use of a drill after completion of drilling, so that breakage of the drill is checked in accordance with the presence of the unusable holes. CONSTITUTION:There is provided a step of forming unusable holes 3 after completion of forming of holes with the use of one and the same drill, with the use of the same drill in a print board outside of an area 2 from which an article is provided. If the number of the unusable holes 3 is, for example, 5 on the left side while 6 on the right side, from the left side, it is shown that one drill is broken before or during machining. In this arrangement, if the order of machining of the unusable holes 3 is determined, it may be clear whether the drill is broken or not. Thus, it is possible to confirm the condition of forming of holes in a print board.
