摘　　要：在对全自动馄饨机折叠成型机构中的主要零件"凸轮导槽"的研制过程中,提出一种基于逆向工程的零件数字化设计与制造新思路,引用三维扫描测试技术、曲面重构技术、曲面参数化建模技术以及CAD/CAM先进制造技术来实现产品的逆向研制过程。制定复杂曲面的数据采集策略、提出不同的点云处理方法、设计曲面参数化建模方案、用现代化的手段对曲面质量和制造工艺进行检验。解决了传统正向设计耗时长、检测难、成本高等问题,可为逆向工程技术在食品机械中的运用提供借鉴。In the CAM guide development process of automatic wonton machine,presents a new method of digital design and manufacturing of complex parts based on reverse engineering.The reverse engineering technology was used to realize the product development by the study of product data acquisition,the point cloud processing,surface fitting,surface parameterization modeling,digital manufacturing stages.Established the strategy of data acquisition,put forward the different method of point cloud processing,designed the scheme of surface parameterization modeling,and inspected surface quality and manufacturing process using modern means.Solved the time-consuming traditional top-down design,test difficulty and high cost,and provided a valuable experience for the application of reverse engineering technology in food machine.
