Abstract
Official abstract text for this publication.
A surface roughening tool includes a cylindrical body and at least one grooving blade outwardly radially projecting from the body and configured to form grooves and peaks into a surface. The surface roughening tool also includes at least one swaging blade outwardly radially projecting from the body and configured to deform the peaks. The at least one swaging blade is aligned with the at least one grooving blade along a circumference of the body.
First claim
Opening claim text (preview).
What is claimed is: 1. A surface roughening tool comprising: a cylindrical body; one or more axial rows of grooving elements outwardly radially projecting from the body, each row situated along a circumference of the body, with each of the grooving elements having a retracted position and an extended position; and one or more axial rows of swaging elements outwardly radially projecting from the body, each row situated along the circumference corresponding to each row of the one or more axial rows of grooving elements, each of the swaging elements having a corresponding fixed distal end forming a fixed swaging circumference concentric with the circumference of the body, wherein in the extended position, each grooving element has a distal end positioned radially outward of the fixed distal ends of the swaging elements to form an extended grooving circumference radially outward of the fixed swaging circumference, and in the retracted position, the distal end of each grooving element is positioned radially inward of the fixed distal ends of the swaging elements. 2. The tool of claim 1 , further comprising an actuator configured to translate each grooving element from the retracted position to the extended position. 3. The tool of claim 1 , wherein in the retracted position, the distal end of each grooving element is positioned radially inward of the circumference of the cylindrical body to be housed in the cylindrical body. 4. The tool of claim 1 , wherein swaging elements of one axial row of swaging elements are interspersed between grooving elements of one axial row of grooving elements. 5. The tool of claim 1 , wherein the grooving elements are configured to form grooves and peaks into a surface when the grooving elements are in the extended position. 6. The tool of claim 5 , wherein the swaging elements are configured to deform the peaks when the grooving elements are in the retracted position.
