摘要
An apparatus for forming recesses on a circumferential surface that defines a cylindrical bore in a workpiece includes a tool holder disposed coaxially with the cylindrical bore; a form roller support retained on the tool holder; a form roller rotatably supported on the form roller support, the form roller including projections on an outer circumferential surface thereof which are configured to form the recesses on the circumferential surface that defines the cylindrical bore in the workpiece. A control assembly is configured to control the form roller support such that the form roller is allowed to be in press contact with the circumferential surface that defines the cylindrical bore in the workpiece at a press contact load of a predetermined value on the basis of a centrifugal force which is exerted on the form roller support and the form roller during rotation of the tool holder.
