The process of radial-axial-ring rolling is a hot forming process that produces rings with high mechanical load capacity. Rings produced using this mechanism are especially deployed as wheel rims for trains, reactor vessels of nuclear power plants, flanges and highly stressed bearing rings, which are used in wind turbines, and have a diameter ranging from 0.1 up to 9 meters. Nowadays, the control uses input data from mechanical- or laser-sensors. For example, the thickness of the rings is measured by the distance between the main roll and the mandrel. The common property of sensors used in conventional controls is the ability to deliver one value per time unit. Therefore, the conventional control cannot detect most of process errors or unintended deformations of the ring. With the research project Image processing in radial-axial ring rolling the Chair of Production Systems develops a solution to expand the conventional control with an image processing system, as it is utilized in other manufacturing processes, in order to obtain additional information about the geometry of the rings and about process behaviour to detect processing irregularities immediately they occur.
