Preliminary investigation on homogenization of the thickness distribution in hole-flanging by SPIF
(Elsevier, 2017-06)
A drawback of the hole-flanging process by single-stage SPIF is the non-uniform thickness obtained along the flange. Multi-stage strategies have been used to improve it, however they increase notably the manufacturing time. ...
