Springback is one of the difficulties of high strength steel (HSS) forming, the majors include three aspects: prediction, control and compensation. This paper focus on springback control of HSS, summarize the reasons and influence factors of HSS springback, And give several solutions in process and design to control the springback. The methods can help to control the springback in design and manufacture.
