Publikováno v: Procedia Manufacturing. 28:207-213
During the conceptual design phase of an aerospace assembly line, the Design Solutions that will meet the functional and industrial requirements are defined. As a result it is possible to define an early conceptual design of the assembly line and its

Publikováno v: ESAFORM 2021.
Recently, hole-flanging by single-stage incremental forming (SPIF) has been proposed as a suitable process to perform hole flanges for small- and medium-sized batches with high flexibility in shape. However, this incremental forming has many differen
