摘　　要：利用三维扫描系统对某空调钣金件进行数据采集,并对采集数据通过点云预处理、特征曲线生成和曲面重构等关键逆向工程技术,最终获得产品的CAD模型。对该重构模型的冲压过程利用Dynaform软件进行数值模拟,根据模拟分析结果修改工艺参数,以得到合理的工艺设计方案,为模具设计提供依据。Data collection is carried out for a certain air-conditioner sheet metal part using 3D scanner, and some key reverse engineering technologies such as preprocess of point clouds, characteristic curve generation and curved surface reconstruction are utilized for the collected data so as to obtain the final CAD model. Subsequently, numerical simulation of stamping process is implemented for the rebuilt CAD model using Dynaform software. Based on the simulated results, process parameters are modified to achieve a reasonable process design, wbicb provides grounds for die design.
