Title:
METHOD FOR PRODUCING ADAPTED FLOW SURFACES
Document Type and Number:
WIPO Patent Application WO2005080754
Kind Code:
A3
Abstract:
The invention relates to a method for producing adapted flow surfaces in the area of a flow entry edge (13) and/or of a flow exit edge of a gas turbine blade. The method comprises at least the following steps: a) creating a nominal milling program for producing flow surfaces in the area of a flow entry edge (13) and/or of a flow exit edge for an ideal gas turbine blade; b) measuring a real gas turbine blade in the area of a flow entry edge (13) and/or of a flow exit edge for the real gas turbine blade; c) creating a milling program, which is adapted to the real gas turbine blade and is used for producing flow surfaces in the area of the flow entry edge (13) and/or of the flow exit edge for the real gas turbine blade, whereby measured values determined in step b) are used for adapting the nominal milling program created in step a) into the milling program for the real gas turbine blade, and; d) producing the flow surfaces on the real gas turbine blades in the area of the flow entry edge (13) and/or of a flow exit edge by milling while using the milling program created in step c), during which, in a first partial step, material in the area of the flow entry edge (13) and/or of the flow exit edge is removed by coarse milling, particularly by roughing and, in a following second partial step, the flow entry edge (13) and/or flow exit edge are/is automatically chamfered by fine milling, particularly by smoothing.
