A scanning device includes a scanner, a fixing seat, a sensor, and a processor. The fixing seat is provided with a positioning groove for fixing a position of a workpiece. The sensor senses whether the workpiece is on the fixing base. The processor is communicatively coupled to the scanner and the sensor and used for receiving signals from the sensor and sending instructions to the scanner. If the sensor senses the workpiece on the fixing base, the processor controls the scanner to scan an identification code on the workpiece. If the sensor does not sense the workpiece on the fixing base, the processor controls the scanner to stop scanning.

A method and a plant for the production of a powdery starting material, which is provided for the manufacture of rare earth magnets, are disclosed. First of all, at least one magnetic material, which is comminuted into a powdery intermediate product with a possibly increased concentration of impurities, and/or at least one alloy including rare earth metal are provided, which includes a low concentration of impurities. A classification of the powdery intermediate product to at least one criterion takes place subsequently, wherein, for the classification of the powdery intermediate product with the increased concentration of impurities, at least one dynamic classifier is provided, which divides the powdery intermediate product with impurities into at least two fractions based on the at least one criterion, wherein at least a high concentration of impurities accumulates in a first fraction and no impurities or at least a lower concentration of impurities than in the case of the first fraction accumulate in a second fraction, and wherein the fraction without impurities or with a low concentration of impurities forms the starting material for the manufacture of rare earth magnets.

A workpiece collecting point unit for a machine tool, in particular for a flatbed machine tool, such as a laser cutting or punching flatbed machine tool, has a placing area for workpieces produced by the machine tool within the framework of a processing plan, a display unit adapted to display information about the workpieces, which are to be further processed and were placed on the placing area, to an operator, and a signal device adapted to output an identification signal indicating to an operator the location of the selected workpiece collecting point unit for placing the workpiece, which is to be further processed, on the placing area. The workpiece collecting point unit can be used inter alia in a process to support a sequence of processing steps for processing workpieces.

A method for assisting a user with sorting workpieces disposed on a sorting table uses a positioning system for determining a spatial position of a user's hand. The position can be determined by a sorting assistance unit worn near a hand of the user and the position of which is detected by the positioning system, or by image-based positioning using one or more cameras. The method comprises providing a position data set that includes the positions of the workpieces produced of the machining plan on the sorting table; by the positioning system, detecting a position of the user's hand and comparing it with the positions of the position data set; identifying at least one workpiece that is paired with the position of the user's hand; and outputting a sorting signal which comprises information about the at least one workpiece paired with the position of the user's hand.
