A method of forming a high precision through hole in a workpiece with a laser beam consists in forming a through hole having a hole section with a diameter equal to a nominal diameter of the through hole, and a hole section with a diameter which is bigger than the nominal diameter of the through hole.

Method of forming high precision through holes in workpieces with a

Measurements of a value of throughgoing openings and workpieces produced during drilling with energy radiation, and particularly laser radiation are performed by producing each opening by several successive energy pulses with focal points offset relative to an axis of the opening, and determining measuring values from a fluid which passes through the throughgoing opening and is supplied to an opening region of the workpiece with a predetermined, constant pressure.
