Abstract: A method of producing holes in a component, in particular of turbomachines, wherein each hole extends from a first, outer surface to a second, inner surface of the component and wherein the method has, for example, the following steps: (i) producing a 3D model of the actual geometry of the component, at least for the region of the holes; (ii) adapting each hole on the basis of the actual geometry of the component; and (iii) generating a production program for each individual hole. In this way, the process quality and with it the quality of the holes increases, because the offset of holes caused by component tolerances is avoided and the drilling funnels are formed according to specification. Furthermore, drilling defects on account of the offset of holes and/or cores can be avoided. Overlapping holes caused by component tolerances are likewise avoided.

Abstract: A method and a measuring system for characterizing a deviation of an actual dimension of a component from a nominal dimension of the component, is disclosed. In an embodiment, the method includes a) determining at least one measured value characterizing the actual dimension at a position of the component by a measuring device; b) making a nominal value available with which the nominal dimension is characterized as a function of the position of the measured value; c) determining a spatial distance between the measured value and the nominal value; d) making a limiting criterion available with which a permissible deviation from the nominal value is characterized as a function of the position of the measured value; and e) determining a tolerance utilization value characterizing the deviation for the measured value as a function of the spatial distance and of the limiting criterion.

Abstract: A method for measuring at least one hole in at least one first surface of a component, in particular for turbomachines, in which at least the following steps are executed: a) provision, using a data processing system, of a target geometry of the component at least for the area of the hole, the target geometry characterizing at least one first target surface of the component in the area of the hole, b) determination, using a measurement system, of an actual geometry of the component at least for the area of the hole, the actual geometry characterizing at least one first actual surface of the component in the area of the hole, and c) determination, using the data processing system, of an actual geometry of the hole on the basis of a deviation between the target geometry and the actual geometry of the component.
