金属板料渐进成形技术现状及发展

Sheet metal incremental forming technology is a new kind of plastic forming technology, it can quickly and economically produce the complex shapes of plank directly from the CAD data without the need for costly die and can be applied to the sample preparation and single piece and small batch production. This paper introduces the principle of sheet metal incremental forming technology, features and process route, and systematacially summarize and analyze the domestic and foreign development present situation from these aspects such as forming mechanism, forming performance, forming accuracy, special parts forming, numerical simulation and the forming surface quality, and also introduces the application of incremental forming and equipment. Finally the problems of sheet metal incremental forming technology and the future research direction were pointed out.
