Abstract

The present application provides a precision self-correction method and system for aircraft panel manufacturing. The precision self-correction method includes: arranging a visual measurement system according to the process information of the aircraft panel; during the workpiece manufacturing process, using the visual measurement system for real-time monitoring to acquire measurement data; and combining the acquired measurement data with the workpiece The theoretical data is compared to obtain the real-time error; according to the real-time error, the process parameters of the flexible tooling or manufacturing equipment are adjusted. The precision self-correction method uses the method of visual measurement of the depth of field data to monitor the deformation, the measurement range is large, and the measurement response is fast; the deformation data is fed back to the flexible tooling, and the flexibility of the flexible tooling is fully utilized to improve the rigidity of thin-walled parts and reduce machining vibration. , thereby correcting the manufacturing accuracy.

Description

technical field [0001] The present application relates to the field of aviation manufacturing, in particular to a precision self-correction method and system for aircraft panel manufacturing. Background technique [0002] Aircraft wall panels have the characteristics of large size (eg 2500mm×30000mm) and thin thickness (eg 60mm), and are typical large thin-walled parts. In the process of aircraft panel processing or assembly, in order to ensure the accuracy of the final panel, the deformation of the workpiece during processing or assembly must be controlled within a certain range. At present, the deformation problem in the manufacturing process of the aircraft panel is usually solved by manual correction after the manufacturing is completed. Under current process conditions, the accuracy of the shape of aircraft panels is ensured by tooling, for example, by the assembly frame during the assembly process. A jig is a rigid positioning technique that has no variability in the...
