Sheet-Bulk Metal Forming

  • Marion MerkleinEmail author
Reference work entry



Sheet-bulk metal forming (SBMF) processes are defined as forming of sheets with an intended three-dimensional material flow as in bulk forming processes (Merklein et al. 2012). As semifinished product, sheets with an initial thickness of 1–5 mm are used and subjected to one or several conventional bulk forming operations. Typical applications of SBMF include the forming of local functional elements on blank parts or the intended and locally restricted alteration of the sheet thickness in order to produce highly functional integrated parts out of sheet metal (Fig. 1) (Mori 2012). Further complexity can be achieved by the combination of SBMF processes with traditional sheet forming operations like bending or deep drawing, which is generally possible for most applications (Merklein et al. 2012). Besides the fabrication of end products, SBMF can also be used to produce tailored blanks with adjusted properties for usage in subsequent manufacturing...
