Interactive Strategy for Adaptive Belt Grinding Heterogeneous Data for an Aero-Engine Blade

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.
