The invention relates to a method for the parametric production of a bore in a component, in particular for the parametric production of a cooling bore in a blade of a gas or steam turbine. According to the inventive method, in a first step (21) an actual wall thickness of the component is measured at the point designated for the bore. Then, at least one parametric geometric value is determined for the bore, based on a comparison of the measured, actual wall thickness with an assumed ideal wall thickness (step 23). The bore is then produced to conform to said value (step 24). The invention also relates to a drilling jig, in particular for carrying out said method and to a component, in which one or more bores are configured according to said method. |
