US Patent:

6566629, May 20, 2003
Filed:

May 7, 1999
Appl. No.:

09/307117
Inventors:

Jeffrey L. Dulaney - Dublin OH
Allan H. Clauer - Worthington OH
Steven M. Toller - Dublin OH
Craig T. Walters - Powell OH
Assignee:

LSP Technologies, Inc. - Dublin OH
International Classification:

B23K 2600
US Classification:

21912174, 21912185
Abstract:

A laser processing method for processing a hidden surface of a workpiece, the hidden surface being disposed within a recess having an opening. The method includes inserting a reflective member into the recess and directing a pulse of coherent energy to reflect off of said reflective member and impact the hidden surface of a workpiece to create a shock wave. Alteratively a surface of the recess may be modified to laser shock process the hidden surface. In one particular embodiment, the reflective member is specifically shaped toprovide diction of a pulse of coherent energy to a hidden surface so that a substantially uniform energy density is applied to the hidden surface. In an additional embodiment, the method is optimized for preventing damage to the reflective member. In one particular embodiment, the reflective member is composed of a fluid.

US Patent:

6512584, Jan 28, 2003
Filed:

Jun 29, 1998
Appl. No.:

09/106793
Inventors:

Mark E. OLoughlin - Galloway OH
Allan H. Clauer - Worthington OH
David W. Sokol - Dublin OH
Jeffrey L. Dulaney - Dublin OH
Steven M. Toller - Grove City OH
Assignee:

LSP Technologies, Inc. - Dublin OH
International Classification:

G01B 1100
US Classification:

356388, 356 32, 427554, 148510
Abstract:

A method of testing the operation of a laser peening system includes providing a sensor in a possible laser beam path, applying a transparent overlay material to the sensor, directing a pulse of coherent energy to the sensor through the transparent overlay material to create a shock wave, and determining a characteristic of the created shock wave with the sensor.

US Patent:

6554921, Apr 29, 2003
Filed:

Jun 29, 2001
Appl. No.:

09/896267
Inventors:

David W. Sokol - Dublin OH
Craig T. Walters - Powell OH
Harold M. Epstein - Columbus OH
Allan H. Clauer - Worthington OH
Jeffrey L. Dulaney - Dublin OH
Mark OLoughlin - Galloway OH
Assignee:

LSP Technologies, Inc. - Dublin OH
International Classification:

C21D 154
US Classification:

148508, 266 99
Abstract:

A method and apparatus for quality control of laser shock processing. The method includes measuring emissions and characteristics of a workpiece when subjected to a pulse of coherent energy from a laser. These empirically measured emissions and characteristics of the workpiece are correlated to theoretical shock pressure, residual stress profile, or fatigue life of the workpiece. The apparatus may include a radiometer or acoustic detection device for measuring these characteristics.

US Patent:

6683976, Jan 27, 2004
Filed:

Apr 30, 2001
Appl. No.:

09/846494
Inventors:

Jeffrey L. Dulaney - Dublin OH
Mark E. OLoughlin - Galloway OH
Allan H. Clauer - Worthington OH
Assignee:

LSP Technologies, Inc. - Dublin OH
International Classification:

G06K 900
US Classification:

382151, 21912185
Abstract:

An image processing system for monitoring a laser peening process includes a laser peening system having a workpiece positioner and a system controller. A video camera is utilized for forming an electronic image of at least a portion of a workpiece. An image processing computer is connected to the video camera, and the laser peening controller includes a program to determine a position of the workpiece.

US Patent:

60490586, Apr 11, 2000
Filed:

Dec 15, 1998
Appl. No.:

9/211568
Inventors:

Jeffrey L. Dulaney - Dublin OH
Allan H. Clauer - Worthington OH
Steven M. Toller - Grove City OH
Assignee:

LSP Technologies, Inc. - Dublin OH
International Classification:

B23K 2600
US Classification:

21912184
Abstract:

A method and apparatus for improving properties of a solid material by providing shock waves therethrough. Laser shock processing is used to provide the shock waves. The method includes applying a transparent overlay to the solid material to be worked. The solid material or overlay is vibrated to release any gas bubbles or solid debris within the transparent layer which could cause localized non-uniform confinement of a pressure pulse applied for a workpiece thereby causing irregularities in the workpiece surface. A pulse of coherent laser energy is the directed to the coated portion of the solid material to create a shock wave. Additionally, the method may include adding a wetting agent or controlling the temperature of the overlay material to reduce the concentration of gas bubbles therein.
