SYSTEM AND METHOD OF LASER DRILLING USING A CONTINUOUSLY OPTIMIZED DEPTH OF FOCUS

摘要

A method of adjusting the depth of focus in laser milling system, there is the laser beam of focal plane including generating, and workpiece is located in focussing plane, wherein the surface of the workpiece and the crosspoint of focal plane at be exposed to laser beam, the position and focal plane of at least one workpiece are adjusted, so that the constant ablation rate workpiece on exposed surface is in entire boring procedure.
