摘　　要： 重点阐述了楔横轧模具数字化设计中有关数字化建模技术、基于知识的设计、并行设计、逆向工程、虚拟设计技术等关键技术。提出了面向制造的特征建模和面向性能分析的特征建模;运用知识工程表示楔横轧模具事例库,并挖掘其内在的规律;采用并行技术,实施楔横轧模具设计与分析的并行、设计与制造的并行;引入虚拟设计思想,构建楔横轧模具的虚拟环境,利用数字化建模阶段产生的信息模型,在三维虚拟环境中对模具进行虚拟装配和虚拟加工。 The key technologies of digitized design for cross wedge rolling mould are introduced which include digital feature modeling, knowledge-based design, concurrent engineering, reverse engineering, and virtual design. Feature-based modeling for manufacture and feature-based for performance analyze are put forward at the same time. Knowledge-based engineering is used to show the cases of cross wedge rolling mould and to discover rules among them. Concurrent engineering is adopted to actualize concurrent between design and analysis, and that between design and manufacture. Virtual design is introduced to constitute virtual environment of cross wedge rolling mould to perform virtual assembly and virtual manufacture.
