  • Publication number: 20180021886
    Abstract: In a laser machining apparatus, an optical member converges a laser beam for machining a workpiece disposed on a mounting surface perpendicular to a first direction and maintains a focal point of the converged laser beam in a focal plane located at a focal position in the first direction. A visible light irradiating device irradiates a visible light in the first direction, thereby projecting a focus target on the workpiece. A pointer beam emitting device emits a pointer beam toward the mounting surface at a prescribed inclination angle. A controller is configured to perform: modifying a positional relationship between the focus target and the pointer beam in a second direction perpendicular to the first direction according to position information related to a projecting position of one of the focus target and the pointer beam in the first direction; and projecting the focus target and the pointer beam onto the workpiece.
