Abstract

A method and apparatus for reworking an inconsistency on a part. Information about the inconsistency on the part may be identified using data generated by a nondestructive evaluation system. A portion of a section of the part in which the inconsistency is located may be removed based on the information about the inconsistency. A profile for the section of the part may be identified. Rework image data may be generated using the profile in which the rework image data comprises a number of patch images. The number of patch images may be projected onto a rework material as a number of patch projections for use in forming a patch to be applied over the section of the part.

First claim

What is claimed is:

1. A method for reworking an inconsistency on a part, the method comprising:
identifying information about the inconsistency on the part using data generated by a nondestructive evaluation system;
removing a portion of a section of the part in which the inconsistency is located based on the information about the inconsistency;
identifying a profile for the section of the part;
generating rework image data using the profile in which the rework image data comprises a number of patch images and a number of hole images;
projecting the number of hole images onto the part as a number of hole projections around the inconsistency;
forming a number of holes in the part using the number of hole projections of the number of hole images on the part around the inconsistency, wherein the number of holes is configured to prevent the inconsistency from increasing in size; and
projecting the number of patch images onto a rework material as a number of patch projections for use in forming a patch to be applied over the section of the part and the number of holes in the part.

2. The method of claim 1 further comprising:
forming a number of patch layers from the rework material using the number of patch projections of the number of patch images on the rework material.

3. The method of claim 2 , wherein the step of forming the number of patch layers from the rework material using the number of patch projections of the number of patch images on the rework material comprises:
cutting the number of patch layers out of the rework material using the number of patch projections of the number of patch images on the rework material.

4. The method of claim 2 further comprising:
applying the number of patch layers over the section of the part having the portion removed to form the patch.

5. The method of claim 4 further comprising:
applying a cover over the patch.

6. The method of claim 1 , wherein the step of removing the portion of the section of the part comprises:
removing the portion of the section of the part in which the inconsistency is located to form a scarf based on the information about the inconsistency.

7. The method of claim 6 , wherein the step of identifying the profile for the section of the part comprises:
pointing a laser beam across the scarf using a laser device; and
identifying the profile for the scarf using the laser beam.

8. The method of claim 1 , wherein the step of removing the portion of the section of the part comprises:
identifying a perimeter image based on the information about the inconsistency;
projecting the perimeter image onto the part as a perimeter projection; and
removing the portion of the section of the part within the perimeter projection on the part to form a scarf using a scarfing tool, wherein the scarf is formed in a number of layers.

9. The method of claim 1 , wherein the step of identifying the information about the inconsistency using the data generated by the nondestructive evaluation system comprises:
identifying image data for the inconsistency on the part using the data for the part generated by the nondestructive evaluation system; and
identifying at least one of a size, a shape, a width, a length, a depth, a height, or a classification for the inconsistency using the image data.

10. The method of claim 9 , wherein the step of identifying the image data for the inconsistency on the part using the data for the part generated by the nondestructive evaluation system comprises:
receiving the data generated by the nondestructive evaluation system; and
processing the data received from the nondestructive evaluation system to identify the image data for the inconsistency on the part, wherein the image data includes at least one of an inconsistency image or a part image.

11. The method of claim 1 further comprising:
generating the data for the part using the nondestructive evaluation system, wherein the data comprises the image data in which the image data includes at least one of an inconsistency image and a part image and wherein the nondestructive evaluation system is selected from one of an ultrasonic system, an eddy current testing system, an x-ray system, a magnetic resonance system, an interferometry system, an imaging system, a thermoelectric system, a thermographic system, or a microwave-based system.

12. The method of claim 1 , wherein the information about the inconsistency comprises at least one of a size, a shape, a width, a length, a depth, a height, or a classification for the inconsistency; the method further comprising:
generating the data for the part using the nondestructive evaluation system in which the nondestructive evaluation system is selected from one of an ultrasonic system, an eddy current testing system, an x-ray system, a magnetic resonance system, an interferometry system, an imaging system, a thermoelectric system, a thermographic system, or a microwave-based system;
identifying image data for the inconsistency on the part using the data for the part generated by the nondestructive evaluation system;
identifying a perimeter image for use in forming a scarf based on the information about the inconsistency;
projecting the perimeter image onto the part as a perimeter projection;
removing a portion of the part within the perimeter projection on the part to form the scarf in a number of layers;
pointing a laser beam across the scarf using a laser device;
identifying a profile for the scarf using the laser beam;
generating the rework image data using the profile in which the rework image data comprises the number of patch images;
forming a number of patch layers from the rework material using the number of patch projections of the number of patch images on the rework material;
applying the number of patch layers over the scarf to form the patch; and
applying a cover over the patch.

13. An apparatus comprising:
a rework manager configured to:
identify information about an inconsistency on a part using data generated by a nondestructive evaluation system in which a portion of a section of the part in which the inconsistency is located is removed based on the information about the inconsistency;
identify a profile for the section of the part;
generate rework image data using the profile in which the rework image data comprises a number of patch images and a number of hole images;

a projection system configured to:
project the number of hole images onto the part as a number of hole projections around the inconsistency, wherein the number of holes is configured to prevent the inconsistency from increasing in size; and
project the number of patch images onto a rework material as a number of patch projections for use in forming a patch to be applied over the section of the part and the number of holes in the part; and

a drilling tool configured to form the number of holes in the part using the number of hole projections of the number of hole images.

14. The apparatus of claim 13 further comprising:
a rework tool configured to form a number of patch layers from the rework material using the number of patch projections of the number of patch images on the rework material in which the number of patch layers is applied over the section to form the patch.

15. The apparatus of claim 14 further comprising:
a cover configured to be applied over the patch.

16. The apparatus of claim 13 , wherein the rework manager is further configured to generate a perimeter image based on the information about the inconsistency and wherein the projection system is further configured to p
