Abstract:
1. A method for the parametric production of a drilled hole in a component, in particular for the parametric production of a drilled cooling hole in a component of a gas or steam turbine, preferably in a blade of a gas or steam turbine, the method comprising: a) providing data of an ideal component or an ideal drilled hole, which originate from a design of the component; b) specifying said data as input variables into a controlling system of a drilling tool; c) measuring an actual wall thickness of the component at the location at which the drilled hole is to be introduced; d) correcting said data based on the actual wall thickness; e) determining at least one parametric drilled-hole geometry value based on the corrected data; f) transferring said at least one parametric drilled-hole geometry value to the controlling system of the drilling tool; and g) producing the drilled hole according to the at least one determined parametric drilled-hole geometry value.
