To process high-quality aero-engine blades, the adaptive belt grinding method, in which an 840D CNC belt grinding machine, an 828D robot, a Win3Ds coordinate measuring machine, and a digital silo are utilized, is applied to the precision grinding of blades. However, due to the informational islanding phenomenon of the processing equipment, the data that are collected by each device cannot be uploaded and downlinked in a timely and effective manner, thereby resulting in poor communication among heterogeneous data. Therefore, this paper proposes an interactive strategy for heterogeneous data for the adaptive processing method of aero-engine blades. First, a mapping transformation of manufacturing information process data, which include the blade order, process, and processing plan, with the XML Schema format is constructed. Second, a data integration model for the grinding process that is based on XML is established, and the standard protocol specification for the manufacturing data is adopted by the XML Schema. Finally, the interaction strategy is evaluated experimentally for typical blades. The experimental results demonstrate that after the heterogeneous data strategy has been implemented, the data interactive transmission is accurate, and the processing blade profile accuracy is within the design range.INDEX TERMS Aero-engine blade, heterogeneous data, data integration, XML, interchange strategy.

In order to obtain high quality aero-engine blades, the adaptive belt grinding method including 840D CNC belt grinding machine, 828D robot, Win3Ds coordinate measuring machine and digital silo is applied to the precision grinding of blades. However, the data collected by each device cannot be uploaded and downlinked in time and effectively, resulting in a problem of poor communication between heterogeneous data information. So, this paper proposes an interactive strategy for heterogeneous data for the adaptive processing method of airborne blades. Firstly, based on the analysis of the heterogeneous data integration characteristics in the processing process, the interactive approach of XML-based integrated aero-engine data integration is studied. Secondly, an integrated model and interaction mechanism for data during the grinding process is established. Finally, the experimental verification of the interaction strategy is carried out for typical blades. The validation results show that after the heterogeneous data is realized, the data interactive transmission is accurate and the processing blade profile accuracy is within the design range.
