<p>The invention relates to 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 blade of a gas or steam turbine. In the case of the method according to the invention, in a first method step (21) an actual wall thickness of the component is measured at the location at which the drilled hole is to be introduced. Subsequently, at least one parametric drilled-hole geometry value is determined on the basis of an adjustment of the measured, actual wall thickness with an assumed, ideal wall thickness (method step 23). The drilled hole is then produced according to the determined parametric drilled-hole geometry value (method step 24). Furthermore, the invention relates to a drilling device, in particular for carrying out the method, and to a component into which one or more drilled holes have been introduced according to the method.</p> |
