The method comprises: detecting the positions (u.sub.o, v.sub.o) and (u.sub.1, v.sub.1) of said photonic beam (L) according to the coordinate axes X, Y on a first and second plane XY, which cut an optical axis X at a first and second point, respectively; comparing the results of said positional detections (u.sub.o, v.sub.o) and (u.sub.1, v.sub.1), and: if there are discrepancies which lie outside the margin of error (p), adjusting the angle of the photonic beam (L) according to the angle and/or the angle in order to overcome said discrepancies; or if there are no discrepancies which lie outside said margin of error (p), considering the angle of said photonic beam (L) as being properly adjusted. The system is adapted to implement the method set out by the invention.

This disclosure relates to a device for monitoring the alignment of a laser beam, comprising: a detector having an opening for passage of the laser beam, at least two temperature sensors which are mounted on the detector, and a temperature monitoring device which is connected to the at least two temperature sensors, for monitoring the alignment of the laser beam relative to the opening. The at least two temperature sensors have a temperature-dependent resistance which either increases as the temperature increases or decreases as the temperature increases, and the at least two temperature sensors are connected in series with the temperature monitoring device. This disclosure relates also to an EUV radiation generating apparatus which has at least one device as described above for monitoring the alignment of a laser beam.

The invention relates to a method for laser remote processing of a component on a fillet, wherein a laser beam is directed by means of a scanner device onto the component and guided over said component. The working range of the laser beam on the workpiece is illuminated with illuminating radiation and is captured by at least one image capturing unit. The illuminating radiation is directed onto the component at an angle of attack which is set depending the fillet geometry of the component. The captured image data are evaluated automatically and, with the aid of the evaluation, if appropriate, an automatic correction of the path of the laser beam is carried out.

An adapter for coupling a laser treatment device to an object for treatment. The adapter has an input side, which may be fixed relative to the laser treatment device, by a locking mechanism and which may be fixed to the object, for alignment of the object relative to the laser treatment device. A scanned laser beam is introduced on the input side, from the laser treatment device, along a beam path to the object with a reference structure. The reference structure lies on the beam path of the adapter and may be optically detected by means of the laser beam scanned over the region.

A laser welder alignment system includes a laser welder, a camera associated with the laser welder configured to capture images of a loaded product within the laser welder, and a controller in communicative association with the laser welder and the camera. The controller receives visualization data from the camera and, based on the visualization data, forms and sends positioning instructions to the laser welder instructing the laser welder so as to position the loaded product at a proper weld start. The laser welder alignment system also verifies proper positioning of the loaded product within the laser welder, and verifies proper rotation of the loaded component by determining whether the rotating product has a wobble that exceeds a pre-defined wobble tolerance.

A system includes a material removal apparatus including a laser. The material removal apparatus is configured to perform a material removal operation with respect to a workpiece. The system further includes a vacuum system configured to provide suction during the material removal operation. The system further includes a manifold configured to remove debris from the workpiece responsive to the suction provided by the vacuum system. The manifold includes a plurality of vanes arranged radially around an open center portion of the manifold. The manifold further includes a shell at least partially enclosing the plurality of vanes.

A computer-numerically-controlled (CNC) machine is configured to (i) measure a power of a beam of electromagnetic energy at a location between a source of the electromagnetic energy and a destination in the CNC machine, the beam of electromagnetic energy traveling from the source to the destination being susceptible to one or more interferences, and the one or more interferences being capable of altering the power of the beam of electromagnetic energy by at least diverting, away from an intended path for the beam of electromagnetic energy, at least a portion of the beam of electromagnetic energy, (ii) detect, based at least on the measured power of the beam of electromagnetic energy being less than a threshold value, an interference of the beam of electromagnetic energy, and (iii) in response to detecting the interference of the beam of electromagnetic energy, perform one or more actions.

An apparatus calibrates a laser processing machine and includes an imaging sensor and a controller. The controller directs output of a beam from the machine's low power pointer laser and directs an actuator at measurement conditions. Images of the beam are obtained by an imaging sensor, and the controller measures a parameter of at least one of the machine's optical components. The controller then outputs an indication of the machine indicative of the measured parameter. For example, the controller can calculate a focus position of the beam from the laser head so the Z-position of the laser head can be adjusted for any discrepancies. In other examples, the controller can determine an offset of the fiber tip of the head so adjustments to operations can be made, or the controller can determine centering of the beam in the head's nozzle so adjustments can be made.

Disclosed are systems and methods to plan a path to form a part using an additive manufacturing system. The additive manufacturing system may include one or more additive manufacturing tools. 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.
