Abstract
The invention concerns a process for checking the quality of formings executed by a machine for forming tube ends, according to which the forming machine is equipped with a force transducer ( ) which is capable of measuring the reactive axial force exerted by the tube on the tool ( ) in a forming pass and, for each forming, in a preliminary learning phase, the maximum reactive axial force exerted by the tube on the tool ( ) is measured, the quality of the executed forming is verified in conventional manner and the value of the maximum reactive axial force obtained in a forming of a quality meeting the required conditions is recorded, then, in each forming pass, the maximum reactive axial force exerted by the tube on the tool ( ) is measured, the value of the said maximum axial force is compared with the recorded reference value and the forming is validated if the measured maximum axial force corresponds to the reference force with a predetermined tolerance.
