Machining template
View Patent ↗An example tool includes a body configured to be secured to a substrate, and a template on or in the body. The template defines at least one of a nominal or a maximum material-removal region. An example assembly includes a substrate defining an aperture, and the tool, including the body secured to the substrate. The nominal material-removal region or the maximum material-removal region are substantially aligned with a respective nominal periphery or a maximum periphery of the aperture. An example technique for machining the substrate includes securing the body of the tool to the substrate. The technique includes substantially aligning the nominal or the maximum material-removal region defined by the template with the respective nominal or the respective maximum periphery of the aperture. The technique includes removing material from the substrate only from a region defined by the nominal or maximum material-removal region.
1. A tool comprising:
a body configured to be secured to a substrate; and
a template on or in the body, wherein the template comprises:
first markings indicating a boundary of a nominal material-removal region; and
second markings indicating a boundary of a maximum material-removal region,
wherein the maximum material-removal region is larger than the nominal material-removal region, and
wherein the maximum material-removal region defines a sacrificial region of the tool.
2. The tool of claim 1 , wherein the body defines one or more windows defining the first markings of the template.
3. The tool of claim 1 , wherein one or both of the nominal material-removal region and the maximum material-removal region are translucent or transparent.
4. The tool of claim 1 , wherein the body is translucent or transparent.
5. The tool of claim 1 , wherein the body comprises at least one of plastic, wood, glass, rubber, paper, metal, non-woven material, or a fabric.
6. The tool of claim 1 , wherein the nominal material-removal region is configured to substantially align with a nominal periphery of an aperture defined by the substrate when the body is secured to the substrate.
7. The tool of claim 1 , further comprising a clip configured to secure the body to the substrate.
8. The tool of claim 7 , wherein the clip comprises at least one magnet configured to secure the body to the substrate.
9. An assembly comprising:
a substrate defining an aperture, wherein a region of the substrate adjacent the aperture exhibits corrosion; and
a tool, wherein the tool comprises:
a body secured to the substrate, and
a template on or in the body, wherein the template comprises:
first markings indicating a boundary of a nominal material-removal region; and
second markings indicating a boundary of a maximum material-removal region,
wherein the maximum material-removal region is larger than the nominal material-removal region, and
wherein the maximum material-removal region defines a sacrificial region of the tool.
10. The assembly of claim 9 , wherein the body defines one or more windows defining the first markings of the template.
11. The assembly of claim 9 , in wherein one or both of the nominal material-removal region and the maximum material-removal region are translucent or transparent.
12. The assembly of claim 9 , wherein the body is translucent or transparent.
13. The assembly of claim 9 , wherein the body comprises at least one of plastic, wood, glass, rubber, paper, metal, non-woven material, or a fabric.
14. The assembly of claim 9 , wherein the tool further comprises a clip securing the body to the substrate.
15. The assembly of claim 14 , wherein the clip comprises at least one magnet securing the body to the substrate.
16. The assembly of claim 9 , wherein the substrate comprises at least one of metal, alloy, glass, ceramic, or plastic.
17. The assembly of claim 9 , wherein the substrate comprises a jet engine front frame.
18. A method comprising:
securing a body of a tool to a substrate, wherein the substrate defines an aperture, and wherein the tool defines a template on or in the body, wherein the template comprises:
first markings indicating a boundary of a nominal material-removal region; and
second markings indicating a boundary of a maximum material-removal region,
wherein the maximum material-removal region is larger than the nominal material-removal region, and
wherein the maximum material-removal region defines a sacrificial region of the tool;
substantially aligning the nominal or the maximum material-removal region defined by the template with a respective nominal or a respective maximum periphery of the aperture; and
removing material from the substrate only from a region defined by the nominal or maximum material-removal region.
19. The tool of claim 1 , further comprising an extended lip configured to conform to a surface of the substrate.
20. The tool of claim 1 , wherein the first markings comprise an edge of one or more windows defining the nominal material-removal region.
