Formability Limits of a SPIFed Stainless Steel

摘要

Single point incremental forming (SPIF) is a new cheep, flexible solution for manufacturing rapid prototypes and products with shorts series. Besides, it has been experimentally proven by different researchers that SPIF assures a higher formability than conventional sheet forming processes, enlarging thus its applicability. The aim of this paper is to examine the forming limits of a stainless steel when it is processed by SPIF. Since sheet thickness has an important role in this process, the analysis is performed for three different thicknesses of metal sheet: 0.8, 1 and 1.2 mm respectively.
