Single point incremental forming (spif) is a new sheet metal forming process with a high potential economic payoff for rapid prototyping applications and for small quantity production. Single-point incremental forming (spif) is a sheet metal forming process that allows manufacturing components without development of complex tools in comparison with stamping process (thibaud et al 2012). Dimensional accuracy of single point incremental forming (spif) is studied with the use of a box-behnken design analysis the dimensional accuracy of this process is determined by comparing parts manufactured using spif with the part drawings used to create the manufacturing toolpaths five factors .
Many experiments have been conducted to investigate the forming limit in single point incremental forming (spif) the forming limit curve (flc) generated from these experiments follows a linear line with a negative slope in the positive minor strain side of the forming limit diagram (fld).
