This invention provides a method for manufacturing a decorated part having a dynamic visual effect of a design that is drawn onto the surface of a work, thus reducing the manufacturing cost. The decorated part is manufactured by a laser-irradiating process, which involves irradiating a laser onto a decorative surface 4, thus forming a design 20 having many laser-processed linear grooves 21 closely aligned in a specific direction F1 on said decorative surface. Also, in the laser-irradiating process, said design 20 is formed such that the angle θ2 that is made by the specific direction F1 and by the direction F2 in which the laser-processed linear grooves 21 are extending is gradually changing into the direction in which such laser-processed linear grooves are aligned.

The first actuator has a first drive coupled to the laser cutting head and configured to move the laser cutting head along a first path. The first drive is coupled to a first counter mass and being configured to move the first counter mass along a second path in a direction opposite the first direction.

A laser device includes a laser oscillator emitting a laser beam, and an optical unit receiving the laser beam and emitting the laser beam to outside. The optical unit includes: a partially transmissive mirror reflecting a part of the laser beam toward the outside while transmitting a remaining part of the laser beam; a diffusion plate diffusing the laser beam passed through the partially transmissive mirror and deflecting the laser beam in a predetermined direction, at a predetermined diffusion angle; and a photodiode receiving the laser beam deflected by the diffusion plate, and outputting an electric signal. The laser device is configured such that deviation of an optical axis of the laser beam is monitored based on an output signal of the photodiode.

A method of confirming an optical axis of a laser processing apparatus includes placing an image capturing unit so as to be movable in X-axis directions, removing a second mirror and capturing an image of a laser beam with the image capturing unit for receiving the laser beam reflected by a first mirror, installing the second mirror and capturing an image of the laser beam with the image capturing unit for receiving the laser beam reflected by a third mirror, and determining whether an optical axis of the laser beam reflected by the first mirror and an optical axis of the laser beam reflected by the third mirror exist in one XZ plane or not on the basis of the captured images and a reference line in the captured images.

A method is provided of controlling a laser processing device with at least one laser. The method includes setting an optical path of the laser processing device by at least one rotatable mirror; a first triggering of the laser at a first point in time so as to generate a first laser spot; continuously adjusting, the optical path of the laser processing device; and a second triggering of the laser at a second point in time so as to generate a second laser spot. The method also includes, before the second triggering: determining the second point in time so that the position of the second laser spot has a desired distance, along the path, to the position of the first laser spot.

A plurality of values measured are relatively compared to determine an optical axis deviation direction in which an optical axis of a measurement beam deviates from a laser beam. Then, a first parallel plate and a second parallel plate are rotated to move an irradiation position of the measurement beam so that an optical axis of the measurement beam is substantially coaxial with an optical axis of the laser beam.

A laser alignment system is used to align an output fiber with a fiber laser, for example, when coupling a feeding fiber to a process fiber using a beam coupler or switch. The alignment system includes a laser alignment apparatus that is coupled at a first end to the output fiber and at a second end to a beam dump/power meter. The alignment apparatus defines a light passage and a light capture chamber along the light passage. When light is not aligned into the core of the output fiber, at least a portion of the light passing out of the output fiber will be captured by the light capture chamber and detected by a photodetector in optical communication with the light capture chamber. By monitoring the readings of the photodetector, the output fiber may be properly aligned with the laser light from the fiber laser.

The additive manufacturing tools may include arc welding tools and non-arc welding tools. The system may also manufacture the part based on the planned path.
