abstract

The present paper is part of the study to develop the advanced computer aided manufacture (CAM) system called the changeable die system (CDS) that applies the cold-forming technique to produce curved metal plates with complex, three-dimensional geometry. This paper focuses on the algorithm of predicting the spring-back behavior using nonlinear finite element method, which is a key element within the framework of the CDS process. The validity of the algorithm is confirmed by comparison with experimental results obtained by the CDS machine in the cold-forming process of curved steel plates.
