Abstract

PURPOSE: To perform numerical control in a drilling machine so that commencement and finish of the center drilling operation is sensed when the drill reaches the surface of a workpiece by sensing means with timer and a predetermined depth of the center drilling can be carried out to a workpiece even having step difference.
