The method involves defining a target geometry of a helical spring by a numerically controlled (NC) control program, and measuring an actual position of a structural element of the spring relative to a reference element at a measuring time point. The actual position is compared with a target position of the structural element at the time point for determining actual position difference that represents difference between the actual position and the target position at the time point. A position of a pitch tool (130) of a shaping device (120) is controlled based on the position difference. Independent claims are also included for the following: (1) a computer numerical controlled spring winding machine comprising a feeding device for supplying a wire to a shaping device (2) a computer program product for executing a method for manufacturing a helical spring. |
