反求工程在复杂冲压零件及成形模具设计中的应用

阐述了复杂冲压零件和成形模具设计反求工程实施中的几个关键技术，即数据采集技术、测量数据的处理技术、曲面重构技术、实体造型技术、落料件的反求技术、成形过程模拟仿真技术等。结合实例，把实施复杂冲压零件及成形模具设计的反求工程分为4个阶段，即认识阶段、设计阶段、分析与修正阶段、加工与调试阶段。提出了冲压反求工程的关键是利用数值模拟仿真软件，对冲压工艺、模具及坯料尺寸等参数进行反求与优化调整。

Application of reverse engineering in complex stamping parts and die design

This paper expatiates on several key technologies in operating reverse engineering of complex stamping parts and forming die design, such as data capture, data processing, surface reconstruction, solid modeling, forming simulation, etc. Moreover, with real cases, Reverse engineering in operating complex stamping parts and forming die design is divided into four main stages, namely, cognition, design, analyses and adjustments, processing and debugging. Through numerical simulation of material forming, parameters of stamping technics,die and blank measure|ment are optimized.
