钣金冲压件CAPP系统中展开图的研究

STUDY ON UNFOLDING DRAWING'S IN PUNCH METAL PARTS CAPP SYSTEM

通过对饭金零件几何信息描述模型和数据结构的分析，提出了利用参数化图形技术和按“父子”关系对零件各型面进行展开，解决了饭金冲压件CAPP系统中展开图自动生成的关键技术。

By analyzing geometry description models and data structures of punch metal parts, this paper presents a method of unfolding each type of surface of parts with parameterized drawings technique and parent-son relation method,and resolves the key technique of unfolding drawing's auto-generating in punch metal parts CAPP system.
