| 摘 要： | 根据并行工程的基本原理,提出了一种基于完整设计信息的高层次工艺规划原型系统.该原型系统以完整的三维设计模型为信息源,因此需开发完善的前置信息处理接口,以获取有效的设计信息并将其转化为制造时工艺分析能直接使用的制造信息.前置处理接口中的设计模型信息提取接口用三维CAD软件的二次开发技术提取完整的零件结构信息;制造特征映射接口用三维特征识别和映射技术将提取的设计信息转换为制造模型.两个接口程序集成后,可获得零件的制造特征树和制造模型信息库,有效地支持HLPP.

| Abstract: | Following the principle of concurrent engineering(CE),a prototype system of high level process planning(HLPP) was proposed.The complete design information of parts was taken as the data source of the HLPP.It is necessary to develop efficient pre-processors to acquire the design information and transform them into manufacturing data that can be used in process analysis.The pre-processor for extraction of design information,which was programmed with the developing package of UG(Unigraphics),extracts data from conceptual design models.The pre-processor of feature mapping transforms the design data into manufacturing data based on 3D feature recognition and mapping technique.The two pre-processors were integrated into a programming package as pre-process interfaces of HLPP. |
