DEEP ROLLING TOOL AND METHOD

An embodiment of a tool assembly includes a robotic assembly, a tool mount, and a non-axisymmetric deep rolling tool. The robotic assembly includes a plurality of linear arms connected in series between a base end and a working end. Adjacent ones of the plurality of arms are connected via a corresponding plurality of multi-axis joints such that the working end is articulated by movement of one or more of the plurality of arms relative to one or more of the plurality of multi-axis joints. The tool mount is connected to one of the linear arms or one of the multi-axis joints at the working end of the robotic assembly. The non-axisymmetric deep rolling tool is connected to the tool mount, and includes a spring-loaded shaft assembly disposed along a first axis. A hub has an upper hub portion adjacent to the distal end of the spring-loaded shaft assembly aligned with the first axis, and a lower hub portion extending along a second axis, forming a nonzero angle relative to the first axis. A roller disk is joined to the lower portion of the hub and is rotatable about the second axis parallel to the second portion of the hub.
