Abstract: A system for first setting a blind rivet and then verifying the correctness of the set comprising a rivet setting tool to set the rivet and computer logic to verify the correctness of the set. The setting tool includes a jaw assembly for holding the stem of the rivet's mandrel fitted to an axially movable pulling shaft. Both the pulling force of the setting tool and the displacement of the pulling shaft are measured and the measurements are interpreted by an integrator to determine the total energy of the setting process. The determined total energy is then compared with an ideal total energy to assess whether or not the set of the particular rivet is acceptable. Other quantitative comparisons may be made against other ideal values.
