Patent ID: 8414264

Claim:
A method for producing a gas turbine component with exposed holes, wherein the gas turbine component has to be coated, comprising: visually predetermining and storing a surface configuration of the component for scanning a position and a shape of the component and the holes before coating, wherein the surface configuration of the component is optically three-dimensionally scanned using a triangulation method, wherein a position of the uncoated component or of the holes is calculated based upon a reference geometry element that is integral to the component; visually three-dimensionally rescanning the surface configuration of the component after coating for exposing the holes covered with coating material; comparing the three dimensional scan of the component before coating with the three dimensional scan of the component after coating to determine a position and orientation of the coated component; and positioning a tool in relation to the position and orientation of the coated component such that the tool exposes the corresponding hole by means of local removal of the coating material.
