Abstract: The
aim of this study is to verify the resulting surface roughness of parts formed
by the Single-Point Incremental Forming (SPIF) process for an AISI 304
austenitic stainless steel. The tests are based on a variation of the
Incremental Forming Process, called SPIF. The tests have been carried out in a
vertical machining center, using a CAD/CAM software. The blanks of AISI 304
steel sheets of
0.5 mm
of thickness have been fixed by a rig and cemented carbide tools with a
hemispherical tip of 8 and
10 mm
of diameter are employed. Some of the tools are PVD multi-coated. A combination
of wall angle and vertical depth simulating critical working conditions has been
set for the process. The finishing roughness parameter has been measured
for the different process conditions. The results found indicate that roughness decrease
with the increase of the vertical depth and with the use
of coating.
