摘　　要：数控渐进成形是一种新兴的板料成形方法,缺乏零件自动放样的专业模块。数控渐进成形放样面的确定是数控渐进成形中十分关键的一步,它影响着成形工件的工艺补充面的设计,以及后续工艺的确定。针对这个问题,在UG二次开发基础上,对零件表面信息进行处理,获得合适的放样面。通过实验验证,该工艺适用于任意形状的零件。The construction of NC incremental forming lofting face is very important, which affects the design of addendum surface of formed workpieee and the confirmation of next process deeply. As a new kind of forming method, NC incremental forming lacks some specialized modules of part auto-loft. To this issue, the idea is dealing with the information of the surface of the part in order to acquire the suited lofting face on the basis of UG secondary development. The method is suitable for any shape of part.
