A method of manufacturing springs by a numerically controlled spring machine includes feeding a wire in a feed direction to a forming device of the spring winding machine by a feed device under control of a control program forming the wire into a spring with the aid of tools of the forming device in a forming operation, the forming device having a mandrel with a mandrel axis oriented at right angles to the feed direction, and windings of the spring surrounding the mandrel during the forming operation, and adjusting a position and/or orientation of the feed device with the aid of a controllable machine axis during the forming.
