The invention relates to a bending machine (M) for bending a workpiece (300), remarkable in that a clamping jaw (511) is supported by a clamping jaw holder (510) receiving at least two clamping jaws (511, 512) arranged back to back,

the clamping jaw holder (510) being fastened to a shelf (513) guided and driven in translation on the bending arm (500),
the support shelves (600) punctually receiving the clamping jaw holder (510) separated from the shelf (513) and to move it on either side of the bending axis transversely to the advance axis of the workpiece (300) to be bent, independently of the bending arm (500) so that the clamping jaw holder (510) can be fastened again to the shelf (513) once the bending arm (500) has been rotated 180 degrees.

The invention also relates to a bending process.

The present disclosure is directed to remedying a non-conforming feature of an aluminum alloy part. A method may include identifying a yield strength as a function of temperature for a designation of the aluminum alloy part, determining a stress to be applied to the feature to re-form the non-conforming feature to within a dimensional tolerance, correlating the stress to the identified yield strength to determine a process temperature of the part upon applying the stress to the feature, determining a time duration for applying the stress to the feature at the determined process temperature, and applying the stress to the feature of the part, the feature being restrained to oppose the stress, while heating the feature to the determined process temperature, and maintaining the application of the stress and the heat to the feature for the time duration in order to reform the restrained feature to within the dimensional tolerance.

A method for bending a pipe by, while sandwiching one portion of the pipe by a gripping device, sandwiching the other portion of the pipe between a pair of bending rolls and by causing the other bending roll to relatively revolve about one bending roll out of the pair of bending rolls, wherein the bending rolls are held by a common movable frame body, the relative revolution is realized by synchronous movement in which rotating movement for rotating the frame body and lateral movement for moving the frame body in a direction (Y-axis direction) perpendicular to a longitudinal direction (X-axis direction) of the pipe are synchronized with each other, and the movement in the Y-axis direction of the frame body is performed such that a position in the Y-axis direction of a center axis of the one bending roll is held and a position in the X-axis direction of a rotating center point of the rotating movement remains same.
