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.

Keywords and phrases: incremental forming, stainless steel AISI 304L, roughness behavior.
