ABSTRACT:
A drill fitted to an adapter is used to drill a hole in a workpiece fixed on a table of a machining center. When the hole drilling is finished, the drill is removed from the adapter, and a workpiece holding jig is fitted to the adapter. Then, the adapter is lowered, and the workpiece holding jig takes the workpiece for which the hole drilling operation has been finished. Following this, the adapter is raised, and the workpiece is temporarily held in the machining center. Then, in this state, the next workpiece is mounted on the table of the machining center. Accordingly, by temporarily holding the workpiece, for which the hole drilling operation has been finished, in the machining center, mounting of the next workpiece is simplified.
