THREE-DIMENSIONAL LASER MACHINE AND METHOD FOR CONTROLLING THE THREE-DIMENSIONAL LASER MACHINE

摘要

A three-dimensional laser machine includes a machine head, a controller for positioning the machine head and controlling an orientation of a nozzle, and a sensor for detecting a distance between a workpiece and the nozzle. The controller is capable of performing a profile control of correcting the position of the machine head based on the detected distance. When the machine head has reached a predetermined position part way through an approach process of moving the machine head from an approach start position to a machining start position while controlling the pose of the nozzle, the controller performs the profile control to move the machine head to the machining start position.
