The manufacture and repair of turbine components consist of a chain of different processes. Many of these processes are carried out manually today, especially in the case of repair. Currently, the repair of blisks is a central issue whenever consideration is given to replacing bladed stages with blisks; however, the feasibility of such a step hinges on the available capabilities for automated repair. A generic data management system has been developed which will constitute the core of automated repair systems for turbine components. The web-based data management system handles the logistics of the components and the accompanying data sets. As a result, different repair processes can be carried out at different facilities without any loss of information (“virtual workshop”). Furthermore, the approach described supports efficient part flow control as well as life cycle monitoring. In addition to the data management developments, existing repair methods have been improved by employing adaptive machining technology that makes use of the geometrical information provided by dedicated scanning systems or inprocess measuring devices and compensates for the part-to-part variation and inaccurate clamping position of the turbine components to be machined.
