介绍一种以AutoCAD为支撑平台的剪板机系列化设计CAD系统。该系统采用了基于事物特性表的可扩充可移植的标准件库管理 ,而向合理化工程的常用图元设计方法以及面向设计全过程的产品装配建模。实现了零件信息和装配信息的动态一致性以及系列化设计过程中设计校核、图纸管理、动态仿真的集成化 ,界面友好 ,使用方便 ,极大地提高了设计效率 This paper introduces a series of CAD system of shearing machine with AutoCAD as support platform. The system uses extensible and portable standard parts library management based on the property table, and the modeling methods of common elements to the rationalization project and product assembly for the whole design process. The dynamic consistency of parts information and assembly information as well as the integration of design check, drawing management and dynamic simulation in series design process are realized, the interface is friendly and easy to use, which greatly improves the design efficiency
