Abstract

This paper presents analysis of the hole flanging process by virtual manufacturing tools. The dependency between initial hole diameter and hole diameter after hole flanging process of sheet metals was numerically analyzed. Hole flanging process formability is analyzed for three different hole diameter, and according to received results dependency between initial hole diameter and collar diameter after forming process is defined. Necessary mechanical properties data of formed material (St 14 according to DIN standard) for process modeling were determinated by experiment. Simulation results show very high coincidence with the empirical data. Also, dependency between maximum punch load and punch stroke for different hole diameters have been defined on basis of simulation outputs.
