1. A system for contouring a ring component, the system comprising:
a frame;
a plurality of forming roller sets mounted to the frame;
each of the plurality of forming roller sets comprising an inner forming roller and an outer forming roller, the forming roller sets being arranged around a system axis such that, in use, the ring component passes between the inner forming roller and outer forming roller of each forming roller set;
wherein each inner forming roller is configured to rotate about its respective inner forming roller axis, and each the outer forming roller is configured to rotate about its respective outer forming roller axis, the inner forming roller axes being closer to the system axis than the outer forming roller axes, the inner forming rollers and the outer forming rollers being adjustable between at least an engagement configuration and a disengagement configuration, wherein, when in the engagement configuration, the inner forming roller and the outer forming roller of each forming roller set define in a space therebetween a forming roller set profile, such that, upon an engagement with the ring component, each forming roller set is configured to form a profile on the ring component based on the forming roller set profile of the forming roller set, the forming roller set profiles of at least two forming roller sets being different from each other; and
an actuating unit operably coupled to the plurality of forming roller sets, wherein the actuating unit is configured to control a configuration of the inner forming rollers and the outer forming rollers of the plurality of forming roller sets so as to control a timing of the engagement and a disengagement of the plurality of forming roller sets with the ring component, wherein the actuating unit is further configured to engage each of the forming roller sets so as to form each forming roller set profile on at least 360 degrees of the ring component, and wherein the timing of the engagement of each forming roller set with the ring component is staggered with respect to each of the other forming roller sets.
