Abstract—Sheet metal bending processes are some of the most commonly used industrial manufacturing operations. The development and optimization of these processes are exhausting and costly. Therefore, FEM may serve as an optimal alternative as the design and quality assurance of sheet metal products in the present study, a commercial legitimate finite element package was used to analyse the three-roller bending of a Steel sheet. Observation with desired curvature radii were established by varying the distance between the two bottom rollers and with respect to the position of the upper one. The developed maps made the rolling process easier and less time consuming. In order to overcome some imperfections of the earlier numerical models of the process and based on the experience gathered with them. The developed system encompasses both sheet metal rolling and pipe bending. An industrial experiment (In Bishno and co. Rabale, Navimumbai) using heightenedapparatus was carried out to validate the numerical model. Residual stress and equivalent plastic strain distributions were also studied. The numerical spring back phenomenon was compared with analytical results.
