Abstract
Incremental forming is a sheet metal forming process that offers flexibility since it does not require any high
capacity press and a set of dies with specified shape for the product, and therefore meets the more and more
increasing demands of small batch production and rapid prototyping. The simplest type of this process, known as
single point incremental forming, proves to be unsuited to achieve components with concave-convex shape.
The aim of the present study is a research on two versions of the process under examination, that is the multistep
process and the one with the use of a pattern, in order to manufacture a component with both concave and convex
features, starting with aluminum alloy sheets.
FE analyses have been carried out in order to foresee the correct implementation of the process. Therefore, some
observations regarding the two process typologies and geometrical analyses, fitted to compare the experimental
profiles with the corresponding ones in the design, have allowed to highlight their pros and cons.
