Research on CAD/CAPP integrated system for automobile wiring harness

In order to improve the efficiency of process planning, a CAD/CAPP integrated system for automobile wiring harness was researched. Firstly, its function model was proposed and every module was stated in detail. Secondly, the key technologies of system development were studied, which include graphic database design, the method of inputting product data and the principle of process planning. On the basis of AutoCAD 2006, a CAD/CAPP integrated system with C/S frame was developed by using ObjectARX. The WYSIWYG (what you see is what you get) technology was adopted to input product information, that is to say, when the automobile wiring harness layout was drawn, both the design information of products and the handles of their corresponding drawing were stored in database. According to the technical parameters, the product data were translated into process steps and instructions, and the manufacture BOM can be automatically generated. Finally, an application instance was elaborated and the results demonstrated that the methods proposed in this paper were reasonable and valid.
