摘　　要：制造底层信息化是制造业信息化的薄弱环节 ,计算机辅助工艺规划 (CAPP)不仅是制造底层信息化的重要研究领域之一 ,也是联系底层信息化与上层信息化的桥梁。工艺设计具有范围广、内容多以及个性化强等特点 ,因此难以实现通用化及商品化 ;而工艺设计是许多制造活动的交汇点 ,是与其他信息系统集成困难的主要原因之一。文章介绍了在CAPP方面的研究特色 ,包括应用框架技术实现开放式CAPP平台 ,通过BOM转换实现集成化 ,以及通过解决行业问题加强CAPP的推广实施等 ;指出了定量化CAPP、基于 3D模型的CAPP以及车间级CAPP将是CAPP的重要发展方向。Computer aided process planning (CAPP) has been regarded as not only an important research area for the informatization on shop-floor level, which presently remains a relatively weaker sector in information-based manufacturing, but also a bridge across the informatization of shop-floor and enterprise levels. For its wide spectrum of tasks with vast amount of contents involved, as well as for its strong necessity in customization to different manufacturing sectors and various manufacturing processes, CAPP has met with difficulties in generalization and commercialization. On the other hand, due to its position as cross point among various manufacturing activities, it has been proven difficult in integrating with other enterprise application systems. This paper introduces some advancements in the R&D of CAPP, including the application of framework technology in the development of an open architecture CAPP platform, system integration based on BOM transformation, as well as promoting the application of CAPP thorough solving typical problems for some specific industries. In addition, some trends in the R&D of CAPP are also pointed out, i.e., quantified analysis and parameter setting, CAPP based on 3D models and CAPP for shop-floor applications are important directins for further R&D in this area.
