Abstract: A method for the bending of a tubular metal article comprising at least the following steps a) determining a bending sequence of the tubular metal article by means of a calculating unit, and b) bending the tubular metal article according to the bending sequence determined during the execution of the step a) is described. During the step a) at least the following sub-steps are performed by the calculating unit: a1) defining an initial configuration and a final configuration of the tubular metal article which differs from the initial configuration by a number N of bends, a2) determining one or more explorative bending sequences as a function of the initial configuration and the final configuration, each explorative bending sequence having a cost and a3) proposing at least one or more explorative bending sequences having minimal costs as the determined bending sequence.

Abstract: A method of bending a metallic article comprising at least the following steps is described: a) executing a relative movement between a bending head having at least one bending group and the metallic article, and b) bending the metallic article by means of an activation of the bending group. During step b), at least a first actuation device actuates the bending group according to a respective motion profile and during the step a), at least a second actuation device actuates a relative movement between the bending head and the metallic article according to a respective motion profile. The method also comprises a step of preparing, during which a respective initial motion profile of the first actuation device and/or of the second actuation device is modified for obtaining the respective motion profile in function of a first parameter and of a second parameter.
