Abstract:
1. A method for reproducing an optimized contour of the leading edges of gas turbine blades, in which a gas turbine blade ( 2 ), by means of a computer-controlled robot ( 10 ), is guided past at least one grinding machine ( 70 , 70 ′) so that as a result of following a movement sequence which is stored in a data memory ( 21 ) the desired contour is achieved, wherein the stored movement sequence is designed for converting a blade from a predetermined statistical average wear state into an also previously determined or calculated design contour; and in that the contact pressure of the gas turbine blade on a grinding disk ( 71 , 71 ′) is measured and taken into consideration in the movement sequence of the robot ( 10 ) so that the desired design contour is achieved regardless of the initial contour and wear of the grinding disks.
