【摘要】 介绍一种折弯加工CAD/CAPP软件系统。该系统具有弯曲件的三维绘制和旋转操作、零件自动展开、弯曲工序的自动编排及加工模拟等功能。文中还介绍了弯曲件的简化、基准面的选择、树状产品数据结构的建立及自动编排等关键技术。更多还原

【Abstract】 A CAD/CAPP software system for CNC bending processing has been introduced, which can draw 3D bend part and rotate the part, automatically determinate the bending sequence and get unbend drawing, simulate processing products. The predigestion of the bending products, the selection of base-face and tree data structure of products, automatic determination of bending sequence etc have also been introduced.更多还原
