摘　　要：金属板材数字化渐进成形技术是国际上刚刚兴起的一种柔性成形技术。介绍了数字化渐进成形的原理、特点及其工艺过程,综合分析了近年来数字化渐进成形技术的研究成果,重点对渐进成形的工艺规划及成形轨迹的优化、对板材成形性能的影响、成形过程的数值模拟、成形精度等方面进行了较系统的归纳和总结,列举了大量的国内外工艺应用及设备情况,探讨了数字化渐进成形技术的发展趋势和有待进一步研究的若干课题。Incremental sheet NC forming （ISF） is a new technology for flexible process that has sprung up in the world used in metal sheet manufacturing. This paper introduced the principles, characteristics and the process of ISF. Then,the literature on ISF was analysed,process planning and tool-path optimization,the formability of sheet metal,numerical simulation on the forming process, dimensional precision were introduced in details. The current applications and equipment for the technique at home and abroad were illustrated. In addition, the trends of study of ISF theory were expected and some important problems left to be solved were suggested.
