“…IF is a process where common and simple tools mounted on CNC machines, instead of complex die sets, are used to deform locally a workpiece. In recent years many studies have been done on IF and many are still in progress with the aim of finding both the most affecting process parameters and the suitable machines and working centres to run experiments and production (Park & Kim, 2002Jeswiet et al, 2005aJeswiet et al, , 2005bDuflou et al, 2005aDuflou et al, , 2005bHirt et al, 2005;He et al, 2005aHe et al, , 2005bAmbrogio et al, 2005;Bambach et al, 2005). Unlike the standard metal forming process, fast production changes are possible thanks to the very simple IF machine configuration.…”
