Author(s): 
Pages: 135-138
Year: Issue:  2
Journal: JOURNAL OF NANJING UNIVERSITY OF SCIENCE AND TECHNOLOGY(NATURE SCIENCE)

Keyword:  冲压工艺冲压件特点计算机辅助设计;
Abstract: 提出了冲压元的概念,阐述了AOS树表示方法,提出利用冲压元与AOS树建立冲压工艺模型.首先描述冲压件各特征的冲压工艺AOS树表达,然后以此为基础描述特征组合的冲压工艺AOS树表达,该描述方式符合工艺设计分阶段、分层次、从局部到全局的规律.最后以一具体的冲压件实例说明AOS树表示方法.
