Simulation and Experimental Investigation of Springback in Air V-Bending Process Using Finite Element Method (FEM)

Abstract:

This paper presents an investigation on cold bending process using simulation and experimental study. The experimental and simulation was performed on stainless steel 304 sheet metal in air V-bending. The factors involved in the process are punch radius, die radius, die gap, punch travel and punch velocity. The aim of this paper is to investigate the factors that affect the springback behavior of stainless steel in air V-bending using Finite Element Method (FEM) software Simufact-Forming^TM version 11.0 and material database MatILDa. The simulation parameters followed the actual setting under consideration of the machine characteristic and friction. The simufact.forming^TM simulation was further verified using hydraulic press machine with determine the desired speed of the forming punch. As the final result, comparison effect of springback between simulation and experiment is presented. It can be concluded that Simufact.forming^TM software can gave fast solution analysis time in prediction of springback affact with good agreement between simulation and experimental.
