Abstract: The invention relates to a method for measuring a tool (1) for roll machining toothed workpieces, wherein a virtual contact points is calculator on a rounded virtual blade of a virtual tool. The relative orientation between the tool axis (B) and the measuring device (11) as well as a translational relative position between the tool and the measuring device are then calculated and adjusted on the basis of the calculated virtual contact point. The measurement is taken on the real blade in the adjusted relative orientation and relative position, and the measurement can be taken in particular using a cylindrical scanning means in the form of a laser beam, wherein the cylindrical scanning means tangentially contacts the virtual blade in the virtual contact point.

Abstract: The invention relates to a method for operating an automatic cleaning device, in particular an industrially usable dishwasher or cleaning and disinfection device with a man-machine interface and a display with buttons. Symbols for the operation and/or an ongoing process are illustrated on the man-machine interface. An interaction of an operator with the man-machine interface is effected via buttons. Depending on the requirements of the operator, context-sensitive help is retrieved via a retrieval, said help accessing a stored information supply comprising image formats, PNG formats, drawings, maintenance lists, spare parts lists and/or databases, which are offered to the operator.
