US Patent 11192204 Laser machining system including laser machining head and imaging device

A machining system includes a laser irradiation device, a camera that captures an image of a workpiece, and a display that displays the image captured by the camera. The machining system includes a robot control device that controls the camera and the display. The camera captures the image of the workpiece before machining. The robot control device calculates a laser-beam irradiation position on the workpiece and virtually displays the laser-beam irradiation position on the display so as to overlap the workpiece image captured by the camera.
