Abstract: To solve problems of pin height calculation and process design in stretch forming, a reconfigurable multi-point tooling process design system was developed. The function module and architecture of proposed system were put forward, and key technologies such as surface orientation, die surface supplement, pin height calculation, blank size and stretching trajectory calculation were discussed and implemented, as well as relevant algorithms. The system development was realized based on CATIA and Component Application Architecture(CAA)secondary development technology. The feasibility and effectiveness were verified by analyzing and calculating on actual aircraft skin part.

Key words: stretch forming, reconfigurable multi-point tooling, process design, secondary development
