US Patent 10987758 Teaching device for laser machining

A teaching device for a laser machining system which performs laser machining on a workpiece while moving an irradiation position of laser light using a robot includes a graphical user interface processing unit which displays machining periods, in each of which machining is performed by irradiating a corresponding one of a plurality of machining points set for the workpiece with the laser light while the robot moves along a machining path, and non-machining intervals between the machining periods of the machining points arranged in time series in a band-like region in a distinguishable manner.
