Abstract

In this study, spring back behaviour of Dp600 (Dual Phase Steel) sheet material was investigated using air V bending technique. As bending parameters, four different punch tip radii and four different sheet thicknesses were used. The spring back values obtained from the experiments were compared with each other. At the same time, the experimental data were analysed with Response Surface Method (RSM) and Taguchi technic. The experimental data and the simulation results were found to be consistent. The signal-to-noise S/N ratio is used to determine the most appropriate parameter of minimum spring back behaviour. Additionally, it is possible to estimate the optimal combination of the bending parameters. The signal-to-noise S/N ratio and the design of experiment (DOE) were utilised for the analysis of the experimental results. It was determined that the effect of these parameters on the air V bending process was based on spring back behaviours.
