Abstract: To develop the reconfigurable tooling rapidly for variant products,the concept and definition of composite tooling were presented.According to the product configuration principle,a fast tooling design method which incorporated tooling retrieval,composite tooling configuration and modular design was proposed,and the detailed configuration process was established.After analyzing the configurability of the assembly jig with box-joint based tooling in detail,a composite tooling model was established.This model was a kind of knowledge model which was enriched with the constraint relations of box-joints,characteristic parameters,empirical equations and configuration rules.It was able to express the design knowledge of product family tooling effectively and comprehensively,which laid the foundation for rapid configuration and reconfiguration.An approach to assembly jig configuration based on the composite tooling was presented,and a system for rapid configuration of airplane assembly tooling was developed.The proposed model and method were validated by the floor-beams assembly of some airplane,and the results indicated that the proposed methods could provide an effective solution to the rapid design of assembly tooling in product family.
