Abstract

Several measures are applied in order to reduce springback but it is not always possible to reduce springback sufficiently. Therefore techniques have been developed to counter springback by modification of the tool shape (overbending). In this paper the smooth displacement adjustment method (SDA) for springback compensation is presented. The discrete springback displacement field is approximated by an L2-projection of suitable continuous smooth functions. Multiplied by a compensation factor the approximating continuous displacement field is applied to the tool surface including the addendum. An application of the new method on an industrial part is demonstrated. The main advantage is the easy handling of the method
