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.
Claims18
A method comprising:
- positioning a cylindrical tool having a body with one or more rows of blades within a cylindrical bore having a surface, the one or more rows of blades including fixed grooving blades mounted to the body, and translatable swaging blades having a retracted position within the body and an extended position with distal ends of the translatable swaging blades being positioned radially outward from grooving blade distal ends;
- forming annular grooves and peaks into the surface with the grooving blades when the swaging blades are in the retracted position within the body such that the distal ends are radially inward of a radius of the body;
- and
- translating the swaging blades from the retracted position to the extended position to deform the peaks.

A method comprising:
- positioning a cylindrical tool at an axial location along a length of a cylinder bore having a surface, the cylindrical tool having a body with fixed grooving blades mounted about the circumference of the body and defining recesses about the circumference of the body to receive translatable swaging blades in a retracted position such that the distal ends of the translatable swaging blades are radially inward of a periphery of the body;
- forming grooves and peaks into the surface at the axial location with the grooving blades when the swaging blades are in a retracted position within the recesses;
- and
- deforming the peaks with the swaging blades when the swaging blades are in an extended position at the axial location,
- wherein in the extended position, each distal end of each of the translatable swaging blades extend radially outward past each distal end of each of the fixed grooving blades.

A method comprising:
- positioning a cylindrical tool having a body with one or more rows of elements including grooving elements and swaging elements, one of the grooving elements and swaging elements being fixed elements with distal ends positioned radially outward of a periphery of the body and the other being translatable elements movable between a retracted position with each of the translatable elements being housed in a respective recess defined in the body such that distal ends of the translatable elements are positioned radially inward of the periphery to an extended position with distal ends of the translatable elements being radially outward of the distal ends of the fixed elements;
- forming grooves into a cylindrical surface with the grooving elements to form peaks therebetween;
- and
- deforming the peaks with the swaging elements.
