ABSTRACT:
A method and apparatus for forming a perforated non-planar object by use of a pulsed energy beam in which the relative position of the object to the pulsed energy beam is determined and the pulsed energy beam is then fired at the object to form a hole based upon the relative position of the object to the pulsed energy beam in accordance with a present hole pattern. The relative position of the object to the pulsed energy beam is then changed, and the determination and firing process is repeated a plurality of times to form a perforated object with a preset hole pattern.
