, that are not observed in single stage incremental forming. They also reported that the formability of hole flanging in SPIF is governed by the fracture forming limit (FFL) and is higher than... longer necks; however, excessively small holes may not allow successful forming of cylindrical flanges. Therefore, there might be a limit on the lower size of hole to successfully form a flange. Moreover......

Thickness distribution of multi-stage incremental forming with different forming stages and angle intervalsLI Jun-chao(李军超), YANG Fen-fen(杨芬芬), ZHOU Zhi-qiang(周志强) (College of Materials Science and Engineering, Chongqing University, Chongqing 400044, China)Abstract:Although multi-stage incremental sheet forming has always been adopted instead of single-stage forming to form parts with a steep......
deep cups are drawn successfully. Key words: 5A06 aluminum alloy; plate; warm reverse deep drawing; forming defect 1 Introduction In order to improve the fuel efficiency and reduce the emissions.... Due to the poor formability and multiple step forming processes at room temperature, it is difficult and uneconomic for the aluminum alloy sheet to form a complex shape. Therefore, warm forming process......
