Abstract

The objective of this paper is to develop a logical procedure to determinethe center roller displacement, in the three-roll bending process, which is required in the fabrication of curved rectangular plates with a desired curvature. To this end, the mechanics of the process was analyzed by both analytical and finite element approaches. Comparisons of the results reveal that a simple analytical procedure, based on the beam theory, yields a reasonably accurate relationship between the center roller displacement and residual curvature. With further development and refinement, the procedure proposed in this work has great promise for practical application, particularlyfor the automation of the process.
