On-the-fly laser drilling offers advantages over percussion drilling. In percussion drilling, a series of shots are fired to generate each hole while the part is stationary, followed by repositioning. During on-the-fly drilling, the part is in continuous motion while the laser fires one shot at a time at each hole and the motion repeats until all holes are formed. This results in: (1) Better material properties and feature quality; due to reduced thermal loading; (2) Smoother axis motion, which reduces vibrations induced onto the laser optics; (3) Less downtime for optics realignment; (4) Higher productivity, as motion 'smoothness' can be translated into higher process speed.
