Abstract and keywords

Multi-stage incremental sheet metal forming (MS-ISF) is a good solution to overcome the maximum forming angle of single-stage incremental sheet metal forming. In order to test the formability of MS-ISF, a novel method to get forming limit diagram (FLD) of MS-ISF was proposed based on changing forming strategies. Aluminum alloy AA1060-O sheet was employed to prove the feasibility of the method. Test results show that the method can provide FLD of MS-ISF which is affected by loading path.
