【摘要】 特征造型技术为产品设计实现标准化、系列化、高效率提供了条件;使工艺规程的制定也比较容易;简化了CAPP决策逻辑。CAD特征造型能从数据库输出CAPP和CAD所需信息,这些信息不仅包括零件的总体信息(形状、尺寸等),还包括加工面的加工信息(粗糙度、加工精度、形位公差等),实现了具有统一数据库、统一界面的集成CAD/CAPP/CAM系统。本文扼要讨论特征造型技术在CAD中的应用。更多还原

【Abstract】 Applying of feature modeling technique is an effective way for product design. It makes the CAPP simple.Feature modeling technique can export the information which CAD and CAPP need.And the information are figure and size of parts,and asperity,precision and tolerance.It makes a integration of CAD/CAPP/CAM system which has a uniform date-base and interface.This paper presents the general view in CAD by applying feature modeling technique.更多还原
