摘要:
为实现冲裁模设计的高效化与智能化,以Pro/E为开发平台,结合范例推理技术,对智能冲裁模CAD系统进行了研究,设计了系统的整体框架,并对组成系统模块的关键技术进行了详细的论述。系统能获得冲裁件的尺寸和公差并进行工艺性检验;能获得最佳的排样方案;系统以编码的方法来反映范例的特征,结合相似性系数计算,能检索到最相似的模具范例;范例改写后,能将符合相似性系数要求的范例进行存储,并能生成模具工程图。

Abstract:
In order to improve the efficiency and intelligence of punching die design, we take Pro/E as developing platform, combining the case-based reasoning technique, to research the intelligent punching die CAD system. The whole frame of the system is designed, and the key techniques of the system modules are discussed in detail. The sizes and tolerance classes of blanking parts can be acquired by the system. Formability check for blanking parts can be acquired and a good blank layout scheme of blanking parts is defined by the system. The features of case are depicted by coding method and the most similar punching die case is confirmed by calculating similarity coefficient. The rewritten case, meeting similarity coefficient demands, can be stored and then the engineering drawing of punching die can be generated by the system.
Key words:  punching die  case-based reasoning  Pro/E
