Numerical control reconfigurable compliant tooling technology

Jig is an important process tooling in aircraft assembly. In order to change the traditional “one to one” assembly mode that one rigid jig only assembles one panel components in aircraft assembly, reduce the number of tooling and develop digital flexible assembly, NC(numerical control) reconfigurable compliant jig that contour board location point is reconfigurable was developed. Its fundamentals and key technologies in design was introduced. Field bus technology was used to make contour board location points numerically reconfigurable. Based on the redevelopment of CATIA, special software to compute reconfigurable data was developed. A whole digital transfer of reconfigurable data was brought about in NC jig application process. The application in practice indicated that NC jig worked stably and reliably as well as meeting accuracy requirements. The aircraft assembly jig was digitalized and flexible, which is of great significance for further study in flexible tooling technology in aircraft digital assembly.
