基于产品定义的图形设计系统

A Structure Design System Based on Product Definition

产品定义数据是实现CIMS的基础,而如何保证数据记录的准确性、一致性,提高系统的使用效率,减少失误又是数据记录、建模的关键。本文着重介绍了溶产品定义与绘图为一体的图形设计系统及其产品定义模型,通过该系统可以直接将信息由CAD系统传递给后续子系统,实现CAD/CAM的集成。

Product Definition Data (PDD) is one of the most important aspects of CIMS.How to keep the accuracy and consistence of the datas and how to improve the property of the system are the kernel technologies of PDD.In this paper,we introduce a structure design system based on Product Definition and its product definition model. Through it,informations about a product can be transported from CAD to CAPP directly to realize the CAD/CAPP/CAM integration.
