Abstract
A method includes positioning a cylindrical tool having one or more rows of blades within a cylindrical bore having a surface, forming annular grooves and peaks into the surface with the grooving blades when the swaging blades are in the retracted position, and translating the swaging blades from the retracted position to the extended position to deform the peaks. The one or more rows of blades includes fixed grooving blades and translatable swaging blades having retracted and extended positions.

A method comprising:
- positioning a cylindrical tool having one or more rows of blades including fixed grooving blades and translatable swaging blades having retracted and extended positions within a cylindrical bore having a surface;
- forming annular grooves and peaks into the surface with the grooving blades when the swaging blades are in the retracted position;
- and
- translating the swaging blades from the retracted position to the extended position to deform the peaks.

A method comprising:
- positioning a cylindrical tool having translatable swaging blades and grooving blades at an axial location along a length of a cylinder bore having a surface;
- forming grooves and peaks into the surface with the grooving blades when the swaging blades are in a retracted position at the axial location;
- and
- deforming the peaks with the swaging blades when the swaging blades are in an extended position at the axial location.

A method comprising:
- positioning a cylindrical tool having one or more rows of elements including grooving elements and swaging elements, one of the grooving elements and swaging elements being translatable between a retracted position to an extended position;
- forming grooves into a cylindrical surface with the grooving elements to form peaks therebetween;
- and
- deforming the peaks with the swaging elements.
