Abstract:

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. 
