| Aircraft parts processing technology is an important link in the product life cycle, it is closely related to the product production and the assembly. At present, the plane process design mostly with 3D product model and 2D process as a basis for drawing, the method reduce processing efficiency and does not conducive to the 3D model of the application. 3D technology model research and the application can be of image and intuitive express product process and easy to understand, avoid secondary design. Therefore, the 3D process model has great significances.This topic of practical engineering application, 3D process model definition digital. The plane with a machine as an example to complete the process of creating 3D model. This paper mainly completed the following work:Firstly, it is based on the thorough analysis of 3D technology, and the research at home and abroad situation. Then it is concluded that the domestic discussed in the engineering practice, especially the deficiencies in the assembly simulation of visualization. After all of this, I expounded the purpose of the research, the meaning and content.Secondly, facing the process information of the plane machine, define the basic theory of 3D technology model , in theory to realize 3D technology model cognition. Puts forward 3D technology model of information express standards, specific definition 3D technology model of the construction of the system.And then, through the theoretical definition, determine the realization of 3D technology model process, the choice of CATIA flat, we use CAA technology realize 3D technology in the second development model, and gives some corresponding Vc++. And describe create 3D technology model of the specific steps.Finally, some useful conclusions is advanced by the full summarized, and puts forward the direction of further research work,it also has some certain reference value for the whole system development. |
