Abstract
Summary A method for determining the optimum forming paths in the roll-bending process of plates by combining the finite element simulation with the fuzzy reasoning is proposed. In this method, the forming conditions in the finite element simulation are automatically changed to attain the desired shape of the plate with the help of the fuzzy reasoning by monitoring the calculated results such as the curvature of the plate, the stress and strain distributions, etc. in each deformation step. To form the front and the rear ends of a plate into a proper curvature by three-roll bending, it is essential to give an appropriate path of the top roll. For this purpose, the optimum motion of the top roll is successively searched for in the finite element simulation. The fuzzy reasoning is used to determine the motion of the top roll by taking account of the effects of the plate thickness, the flow stress and the difference between the desired and the calculated curvatures. It is shown that the decrease in the curvature near both ends of the bent plate is prevented by the use of the present method.
