Device for maintaining gas turbine blades

摘要

The method involves passing a gas-turbine blade (2) by one or multiple grinding machine or machines (70,70') with the aid of a computer-controlled robot (10). A stored movement process is designed to convert a blade from a previously determined statistical mean wear state to a previously determined design contour. The contact pressure of the gas-turbine blade on a grinding disk (71,71') is measured and is taken into account in the movement process of the robot such that the desired design contour is achieved irrespective of the initial contour and wear of the grinding disks. An independent claim is also included for an arrangement for the execution of an optimized contour re-creation method.
