A system that uses a scalable array of individually controllable laser beams that are generated by a fiber array system to process materials into an object. The adaptive control of individual beams may include beam power, focal spot width, centroid position, scanning orientation, amplitude and frequency, of individual beams. Laser beam micro scanner modules (MSMs) are arranged into 2D arrays or matrices. During operation of the MSMs, a fiber tip that projects the laser beam is displaced along the x and y-axis in order to scan the focal spot. Each MSM within a matrix can process a corresponding cell (e.g., one square centimeter) during focal spot scanning, and the plurality of MSMs may be operated in parallel to process a plurality of corresponding cells (e.g., with a 10×10 matrix of MSM, 100 cm.sup.2) without rastering or otherwise repositioning the assembly over the build surface.

The invention relates to a sorting system (100) for a machine tool for separating parts, in particular a laser cutting machine (200), having a gripper (110) that can be moved over a workpiece region (30) and is configured to receive cut parts (10) from the workpiece region (30), and an intermediate store (120) that can be moved over the workpiece region (30) and is configured to receive cut parts (10) from the gripper (110) and to unload the cut parts (10) into a store (40).

An NC device 20 determines, in a case where a size of an opening forming region in a predetermined direction is smaller than a predetermined maximum value, that the opening forming region is a first opening forming region, and determines, in a case where the size of the opening forming region in the predetermined direction is larger than a predetermined minimum value, that the opening forming region is an opening forming region where a scrap interfering with a laser head 16 is formed. In a case where the size of the opening forming region in the predetermined direction is smaller than the predetermined maximum value and larger than the predetermined minimum value, the device determines that the opening forming region in an interference width added region obtaining by adding a predetermined interference width to the opening forming region is a second opening forming region, and processes the second opening forming region prior to processing of the first opening forming region.

Sensor data generated by a sensor of a computer numerically controlled machine can be compared with a forecast. The forecast can include expected sensor data for the sensor, over a course of an execution plan for making a cut with a movable laser cutting head. The sensor data can be generated during execution of the execution plan. During execution of the execution plan, the sensor data can be monitored and a deviation of from the forecast can be detected. It can be determined, based on the detecting, that an anomalous condition of the computer numerically controlled machine has occurred. Based on the determining, an action can be performed.

The invention concerns a process for treating a workpiece, preferably for shaping a workpiece by ablating material, by a liquid jet guided laser beam. The process comprises the following steps: Production of a liquid jet by a nozzle; impinging the liquid jet on a reference surface allocated to the workpiece, whereby an intersection of the liquid jet with the reference surface defines a liquid jet-footprint; effecting a displacement between the liquid jet and the reference surface, whereby the liquid jet-footprint evolves to a trace along a trajectory associated with the trace during the time frame, wherein the trace covers a trace-area; irradiating the workpiece at least during part of the time frame with a laser beam coupled into the liquid jet, preferably for ablating material such that the trace has at least one overlap-area, wherein each of the at least one overlap-areas is defined by an associated common area of an associated second length-section of the trace and an associated first length-section of the trace and wherein the workpiece is irradiated by the laser beam along at least one of the length-sections. It concerns further a computerized numerical control (CNC) program for controlling a liquid jet guided laser machining device and a computer readable medium containing such a CNC program. Further, it contains a computer program for generating the above mentioned CNC program. Finally the invention concerns a liquid jet guided laser machining device to perform the above mentioned process.

An optical device that is intended for laser treatment of internal surfaces of a covering part of the leading-edge type, including a collimator that is intended to be connected to a laser source via an optical fibre to produce a laser beam having a collimated and flat spatial pulse profile, a cylindrical lens that is configured to focus the laser beam along a spatial line that is transverse to the propagation of the laser beam thus forming a line-laser-beam, a reflecting optical component that is configured to be able to be introduced into the interior of the covering part and to uniformly reflect the line-laser-beam onto at least one internal surface of the covering part and in directions of incidence that are almost normal to at least one internal surface.

A method and apparatus for applying a cladding layer to a surface of a component uses a cladding tool having a maximum reach less than the size of the surface. Geometry of the surface is segmented into a plurality of tessellated segments, each of which has a peripheral extent determined by a maximum reach of the cladding tool. A nominal tool subpath for each tessellated segment is generated, and then combined to generate a nominal tool path for depositing the cladding layer on the surface. The surface is clad using the nominal toolpath, including a process of adjusting the nominal tool path to an adjusted tool path that accounts for dimensions of the bead to be deposited by the tool to match an edge of the bead to be deposited with an edge of a previously deposited bead.
