Abstract
A method is provided for the confirmation of the diameters of plural drills of different diameters in a PWB working machine in which the drills are interchangeably mounted to perform drilling. The method comprises storing, with respect to each of the drills, data on whether or not the drill has already been used, checking the data of one of the drills upon drill replacement, and measuring the diameter of the drill only where the drill has not previously been used.
