Abstract

Sheet metal forming processes, such as brake bending, rubber forming, and punch stretch forming, have significant use in manufacturing aircraft, automotive, and appliance parts. Computer-aided modeling and simulation of these processes provides information for production planning, for equipment and tooling selection, and for predicting potential failure during forming. Mathematical models and computer programs are developed to analyze and simulate these widely used sheet forming processes. The validity of these process models and the accuracy of the predicted results were evaluated by laboratory and production site tests.
