摘　　要：采用逆向辅助技术,对一款结构较为复杂的某制品进行快速而精确的模具设计,先利用三维激光扫描仪得到其点云数据,再使用Imageware软件进行点云处理和曲面重构,然后在UG软件中进行三维造型及相应的优化设计,最终以最合理的设计方法得到完整的模具图,用于后续的模具加工与生产。结果表明,此方法既能提高模具及产品的精度,又能大大缩短设计周期,节约成本。尤其对一些具有结构复杂、曲面要求高或者缺失原始几何数据的制品,此方法更能发挥其优势。Using reverse assistive technology for fast and precise mold design of some complex structure products,using 3D laser scanner to get point cloud data,using Imageware software for point cloud processing and surface reconstruction,then 3D modeling in UG software and the corresponding optimal design were made. The full mould drawings of final design with the most reasonable method was got for subsequent mould processing and production. The results show that this method can not only improve the precision of the mould and products,and can greatly shorten the design cycle,save cost. Especially for some complex structure, high surface requirements or lost original geometric data of the products,it can exert more advantage.
