The ablation phenomenon occurs when a pulse laser irradiates carbon-fiber-reinforced plastic (CFRP) by energy absorption. Laser ablation processing makes uses of this phenomenon for machining. One of the most important problems about this process is to improve this processing speed. Therefore, it is necessary to evaluate how these factors such as laser energy and frequency, feed speed and atmospheric gas affect this processing. Until now, some experiment systems have been developed for studying these effects. In particular, we designed the vacuum chamber with XYZ-automation stage and sealed gas nozzles. By concentrating laser light to a material on the stage with these equipments, we succeed in punching and cutting CFRP.
