Abstract

Now that the simulation of deep drawing processes has become more reliable the virtual compensation of the forming tools has become reality. In literature, the Displacement Adjustment (DA) algorithm has proved to be most effective. In this article it is shown how the compensation factor, required for (one-step) DA depends on material, process and geometrical parameters. For this an analytical bar stretchbending model was used. A compensation factor is not required when DA is applied iteratively and the products geometrical accuracy is improved further. This was demonstrated on an industrial part. The compensation varies over the product, leading to a reduction in shape deviation of 90% and more, a result that could not have been achieved with one-step compensation
