The influence of Part Geometry and Friction on the Accuracy of Bending

In manufacturing of working parts by metal forming there are a number of various methods, owing to sorts and largeness of parts as well as the demands for form and accuracy that cause different procedures and ways of bending process. Elastic part of deformation causes aberration of form and accuracy in bending. The important criterion in validation of bended parts presents the aberration of bending angle. As a measure for angle accuracy, it can be taken into account a relative error of bending angle. For the improvement of accuracy it is used a model, that compensate the mechanical spring back. 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.
