1.Introduction
A progressive die is used worldwide for mass production of
sheet metal parts.Design of progressive die is a complex and
highly specialized procedure and typically progressive die design
takes 20% of the lead time from the concept design to the final
stamping manufacture.The diverse nature of products produced
by progressive die demands a high level of knowledge on the part
of the die designer that can only be achieved through years of prac-tical experience.Checking the design features of sheet metal parts,
design of strip-layout,selection of die components,selection of
materials for die components; and modeling of die components
and die assembly are major activities for designing a progressive
die.The traditional methods of carrying out these tasks require
expertise and are largely manual and therefore tedious,time con-suming and error-prone.The quality of die design depends to a
large extent on the designer’s

简介
顺序冲模法在世界上被广泛用于钣金零件的大规模生产.顺序冲模的设计不仅需要复杂和高度专业化流程,而且从概念设计到最终冲压生产,一般的顺序冲模需要耗费20%的生产提前期.顺序冲模能生产出丰富多样的产品,这就要求冲模设计者具有从多年的实际经验中获得的专业知识.设计顺序冲模的主要工作内容包括：检查钣金零件的设计特点,工序排样设计,模具元件的选择,模具元件所用材料的选择,模具元件和模具生产线的建模.传统方法需要设计者具有专业知识,人力工作量大而乏味,耗费世间,容易出错.过去模具设计的质量很大程度赖于设计者的技术,经验和知识.如今许多研究者正在为顺序冲模开发计算机辅助系统.（更多专业译文,找Q ⑨①〇①⑧〇〇⑧③）
