| As assembly plays a very important role in the product life cycle, it is one of the primary factors which affect the product performance, the quality, the development cycle and cost. At present, two-dimensional data are mostly used in assembly process design system. Compared with three-dimensional models, two-dimensional models are not intuitionistic and have bad visibility. Therefore, research on assembly process structure design with 3D visualization has vital significance. This paper studies the visible mapping in three–dimension from design structure to assembly process structure.It is needed to convert the design structure in CAD system to assembly process structure for assembly process structure design, as the result of the differ between design structure and assembly process structure. In this paper a method of mapping from design structure to assembly process structure is represent.To implement the above method, the source of the three-dimensional models and the display of three-dimensional models must be solute. At present, in enterprises the parts of a product are probably designed in different CAD systems which causes the product has no complete assembly model. The data of models in different CAD systems must be integrated in a system to complete the product assembly. And for assembly process design, the data of models in different CAD systems is unnecessary and excessive, which needs lightweight. A lightweight interface oriented different CAD systems which can transfer different models in different CAD system to uniform models which is lightweight is designed and implemented. And by this interface, the lightweight files can be browsed and a three-dimensional visible mapping from design structure to assembly process structure is implemented.In the above mentioned three-dimensional component, a three-dimensional visible system is studied and implemented in this paper, and the validity and validity of the system is testified by an instance. |
