Abstract
A method and apparatus for processing a portion of a workpiece. At least one roller is supported on a rotatable member rotatable about a main axis to be radially moved to and from the main axis. The workpiece is supported to position a central axis of the portion to be processed at least one of offset from and oblique to a forming target axis overlapping the main axis. Then, at least one of the workpiece and the roller is driven to be rotated relative to each other about the forming target axis, while the roller is moved radially toward the forming target axis, with the roller being in substantial contact with a surface of the portion to be processed. As a result, the portion to be processed is formed into a changed diameter portion having the forming target axis.
