Abstract
Apparatus is disclosed in a system for drilling holes with a laser beam in a plurality of discrete moving workpieces carried by a support which moves each workpiece sequentially along a predetermined path at a predetermined velocity, the apparatus including means for sequentially tracking along a portion of such path each workpiece being drilled seriatim by the laser beam. This tracing apparatus includes means for directing the laser beam generally transversely of the direction of movement of the workpiece on the support and a mirror for folding the transversely directed laser beam toward the workpieces with means for oscillating the folding mirror synchronously with the movement of the workpiece to track the workpiece as it moves.
