Abstract: A method processes a workpiece using a device. The device has a processing machine configured for three-dimensionally processing the workpiece, and a tool head having a tool. The tool head is movable about at least a first axis and a second axis. The method is carried out by the device. The method includes: capturing input data concerning a contour of the workpiece, a contour of the tool head, a distance between the tool head and the workpiece, the first axis, and the second axis; processing the input data to form feature data; processing the feature data in a machine learning algorithm of the device; and outputting a forecast from the machine learning algorithm regarding a collision of the tool head with the workpiece or some other part of the processing machine.

Abstract: A chuck for a rotatable tool, such as a drill, a screw tap and the like has a chuck sleeve receivable in a machine and having a central receptacle, a sleeve provided for a tool and releasably inserted in the receptacle, the sleeve having a central main passage for a cooling and/or lubricating medium and grooves for supplying the cooling and/or lubricating medium in a longitudinal direction and outwardly of the tool, the sleeve having an axial opening adopted to extend over a whole length of a shaft of the tool for holding the shaft, the grooves for the cooling and/or lubricating medium in the sleeve being provided on an inner side of the axial opening and extending axially over a whole length of the sleeve, the grooves at one end communicating with the central passage in the chuck sleeve and at another end being axially freely open.
