Abstract

Method of bending on press brakes or similar whereby the desired result, e.g. the desired final bending angle, is input into a computer with a connected neural network that has "learned" the relations between the parameters of bending procedures, after which the computer, with the help of the neural network, controls the movement of the pressing tool to obtain the desired result.
