Improvement the accuracy of side and bending in two stages

The influence of mechanical spring back on bending angle can be eliminated, if it is in certain range of opposite direction and the same amount. The following elements exter influence on bending: press-brak, die, work piece geometry, product properties and friction. This paper analysis the influence of friction on the accuracy of bending and bending in two stages.
