Many service offers for the repairing of damaged gas turbines parts are still handled like individual cases with an respectively high amount of manual operation, communication and handling. This is notable in the acquisition of information for the worn-out parts, the requirements definition for the scan order, the manual creation of the toolpaths and the data handling along the whole process. Every process step requires a lot of communication and exchange of data between the involved employees. Further there is no tracking of the parts, just very rare documentation about the repair process of the single component and data distributed in different systems. An overview about the repair process of a certain type of component is missing and therefor it is difficult to improve and scale the repair process. A comprehensive digitized repair process chain, the therein given possibility to automate the process and a centralized documentation of all repair processes have a great potential to save resources and time.This paper proposes as a first step a method to communicate the scan requirements for a component in a formalized and digitized manner. The aim is to facilitate the communication between engineering and the scan operator and to document the requirements at the same time. The method is based on the result of interviews with different departments who work with the scan data. The requirements can be split into 3 different categories: formal information about the scanned part, the regions on the part to be scanned and further specifications for the scan. The method can be realized with a digital questionnaire, which allows the operator based on the answers to choose the right scan strategy, to scan the necessary areas and to store it on the requested location.Because all involved departments work within the CAx-environment and are very familiar with it, it is an adequate place to include the method there. To overcome the problem of different CAx-Versions of NX (in the different remanufacturing sites) we made use of the cloud-based CAx-environment Nx 2Go. This cloud-based, pay per use&nbsp;CAx-solution allows access from all internet connected electronic devices and can be easily entered from the shop floor or the field, wherever the scan of the component should be realized.As a next step it is planned to define scan specific features, like Product and Manufacturing Information (PMI) for GD&amp;T, to facilitate the handling of scan data within the CAD-System.

ASME 2021 Advanced Manufacturing & Repair for Gas Turbines (AMRGT2021)

Supporting the need among researchers worldwide for additional online and multimedia content, ASME now offers the ASME Conference Video Collection. This platform will collect and provide long-term access to conference presentation videos, encompassing all technology areas within ASME's technical conference and events program. About 30,000-40,000 engineers across all mechanical engineering and related disciplines participate in ASME conferences each year. This includes authors of approximately 6,000 to 8,000 technical papers published by ASME, the majority of whom also submit video presentations for our virtual conferences. The video collection will be available as an add-on to existing product packages or as a separate subscription.
