TL;DR: In this article, a scribing wheel was used for texture processing, and the wheel was rolled while pushing its edge onto the sliding face of a slide member to be processed, so that a plastic deformation by a roller burnishing was caused to form the rolling traces of fine grooves 10, 10' and 10" in a sliding face.
Abstract: PROBLEM TO BE SOLVED: To provide a texture processing method capable of forming a texture pattern excellent in form accuracy by a novel method.SOLUTION: A scribing wheel 11 having a tip formed along a circumference ridge line is used, and the wheel 11 is rolled while pushing its edge onto the sliding face of a slide member 3 to be processed, so that a plastic deformation by a roller burnishing is caused to form the rolling traces of fine grooves 10, 10' and 10" in the sliding face thereby to process a texture pattern.SELECTED DRAWING: Figure 4

TL;DR: In this paper, the authors present a tool diameter following mechanism connecting the shank and the mandrel, having a lead groove formed spirally in a front portion of the tool, a pin member capable of moving along the lead groove, insertion hole formed in a mandrel to insert the pin member therein, and a biasing unit biasing the tool forward.
Abstract: Provided is a roller burnishing tool device including a shank; a housing connected to the shank, a connected position of the housing relative to the shank being adjustable; a roller support member supported to be capable of rotating relative to the housing and attached to follow a movement of the housing in a case of adjusting the connected position; tapered rollers supported by the roller support member; a mandrel having a tapered portion matched with the tapered rollers and movable relative to the roller support member; and a tool diameter following mechanism connecting the shank and the mandrel, having a lead groove formed spirally in a front portion of the shank, a pin member capable of moving along the lead groove, a pin member insertion hole formed in the mandrel to insert the pin member therein, and a biasing unit biasing the mandrel forward.

TL;DR: In this paper, the authors provide a computational evaluation of the roller burnishing process to address the permanent deformation needed to introduce a desirable residual stress state, using a series of incrementally applied pressure loadings and finite element methodology.
Abstract: The possibility of stress corrosion cracking (SCC) in regions of tensile residual stress introduced by weld deposited material has been a concern where environmental effects can reduce component life. Roller burnishing, a form of mechanical cold-working, has been considered as a means of providing for residual stress state improvements. This paper provides a computational evaluation of the roller burnishing process to address the permanent deformation needed to introduce a desirable residual stress state. The analysis uses a series of incrementally applied pressure loadings and finite element methodology to simulate the behavior of a roller burnishing tool. Various magnitudes of applied pressure loadings coupled with different size plates and boundary conditions are examined to assess the degree and depth of the residual compressive stress state after cold working. Both kinematic and isotropic hardening laws are evaluated.

TL;DR: In this article, Alexander described a roller burnishing tool, which consists of a mandrel with a frusto-conical portion surrounded by tapered rollers in a cage and formed at its other end for attachment to a machine tool.
Abstract: 931,242. Burnishing by rolling. GEORGE H. ALEXANDER MACHINERY Ltd. Oct. 12, 1961 [Oct. 12, 1960], No. 34938/60. Class 83 (4). A roller burnishing tool comprises a mandrel 11 provided at one end with a frusto-conical portion 13 surrounded by tapered rollers 22 in a cage 23, and formed at its other end 12 for attachment to a machine tool, and a housing 16 which is rotated on a thread 14 to move the roller cage 23 axially relative to the mandrel by means of a sleeve 24 to alter the overall diameter of the ring of rollers. The sleeve is spring- loaded against the housing 16 with or without a thrust bearing 28, and indicia 18 and 19 allow precise adjustment of the tool. The included angle of each roller is slightly greater than half the conic angle of the frusto-conical portion 13, the rollers may be set slightly skewed to the axis of the mandrel, and the cage 23 end portion 13 can be removable to substitute differentsized members.
