Abstract

The present invention is directed to method for setting a formed helical compression spring. At the out set, parameters are measured to determine a reaction force axis of a formed helical compression spring. Next, A target reaction force axis of the spring is compared with the reaction force axis determined by the measured parameters to provide an error between the target reaction force axis and the detected reaction force axis. Then, a tilt angle of at least one of the compression plates tilted to an end plane of the spring is provided, in at least one direction on a plane including a coil axis of the spring, on the basis of the error between the target reaction force axis and the detected reaction force axis. Then, at least one of the compression plates is actuated to pressurize the spring, with at least one of the compression plates tilted to the end plane of the spring by the tilt angle.
