Abstract

A method and apparatus for identifying locations for holes for a stackup of parts. In one illustrative example, a required edge distance for a hole for the stackup of the parts is identified. A measurement tool is selected based on the required edge distance identified for the hole. The measurement tool comprises a circular section having an edge and an indicator centrally located with respect to the edge of the circular section. The edge of the circular section of the measurement tool is associated with a part in the stackup of the parts. A location on the part for a center of the hole for the stackup of the parts is identified using the indicator.

First claim

What is claimed is:

1. An apparatus for measuring a minimum edge distance between a first edge of a stackup of parts and a location where a fastener hole is to be drilled in the stackup of parts, the apparatus comprising:
an elongate member having a first end and a second end;
a circular section having a second edge and coupled to the first end of the elongate member;
an indicator centrally located with respect to the second edge of the circular section, wherein a distance between the second edge and a center of the indicator is predetermined to be the minimum edge distance for the stackup of parts; and
a plurality of concentric circular markings surrounding the indicator.

2. The apparatus of claim 1 , wherein the indicator is configured to indicate a location for a center of a hole.

3. The apparatus of claim 1 , wherein the indicator is selected from one of a hole and a marking feature.

4. The apparatus of claim 1 , wherein the elongate member, the circular section, and the indicator form a measurement tool.

5. The apparatus of claim 4 , wherein the measurement tool is one of a number of measurement tools, wherein each measurement tool in the number of measurement tools has a different circular section with a different radius.

6. The apparatus of claim 1 , wherein the elongate member and the circular section are comprised of a material selected from one of steel, aluminum, polycarbonate, plastic, metal, metal alloy, copper, titanium, fiberglass, and glass.

7. The apparatus of claim 1 , wherein the indicator comprises a pair of intersecting slots, wherein the pair of intersecting slots is at a center of the concentric circular markings.

8. The apparatus of claim 1 , wherein the indicator is configured to receive a tool.

9. The apparatus of claim 8 , wherein the tool comprises a drill.

10. The apparatus of claim 1 , wherein the second edge comprises a straight cross-sectional profile.

11. The apparatus of claim 1 , wherein the second edge comprises an oblique cross-sectional profile.

12. The apparatus of claim 1 , wherein the second edge comprises an arcuate cross-sectional profile.

13. The apparatus of claim 1 , wherein the second edge comprises an angular cross-sectional profile.

14. The apparatus of claim 1 , wherein the second edge comprises a combination of at least two of a straight cross-sectional profile, an oblique cross-sectional profile, an arcuate cross sectional profile, and an angular cross-sectional profile.

15. The apparatus of claim 1 , wherein the indicator is countersunk.

16. The apparatus of claim 1 , wherein the circular markings are circles.

17. The apparatus of claim 16 , wherein the circles are concentric with each other and with the indicator.

18. The apparatus of claim 1 , wherein the predetermined distance is indicated on a surface of the elongate member.
