Description:
<jats:p>In this paper the influence of the bending effect in the formability of AISI 304 metal sheets in incremental forming is analyzed. For this purpose, a series of single point incremental forming tests were carried out using a variety of tool diameters and step downs. The spifability (formability in single point incremental sheet forming) of the metal sheets was studied in the light of circle grid analysis by means of the 3D deformation digital measurement system ARGUS®. The results show the importance of the bending effect, induced by the tool radius, in the enhancement of formability in incremental forming compared to conventional forming processes.</jats:p>
