Abstract

A fixture to facilitate positioning a gas turbine engine component. The fixture includes a stationary portion including at least one stationary datum locator extending outward from the stationary portion. The fixture also includes a movable portion including at least one movable datum locator extending from the movable portion. The at least one movable datum locator is substantially parallel to each of the at least one stationary datum locator. The movable portion is movable in a direction that is away from the stationary portion.

Claims

1. A method for manufacturing a component, said method comprising:

locating a plurality of pre-determined internal features defined across an internal surface of the component;

determining a model of the component based on the located internal features;

manufacturing a portion of the component based on the model.

2. A method in accordance with claim 1 further comprising positioning the component relative to a fixture based on the located internal features.

3. A method in accordance with claim 2 wherein locating a plurality of pre-determined internal features comprises locating the internal features using at least one datum locator.

4. A method in accordance with claim 2 wherein locating a plurality of internal features comprises using at least two datum locators extending from a stationary portion of the fixture and at least one datum locator extending from a movable portion of the fixture.

5. A method in accordance with claim 2 wherein positioning the component relative to a fixture comprises positioning the component to substantially prevent movement of the component relative to the fixture.

6. A method in accordance with claim 4 wherein positioning the component relative to a fixture comprises:

moving a movable portion of the fixture in a first direction; and

moving the movable portion of the fixture in a second direction.

7. A method in accordance with claim 6 wherein moving the movable portion of the fixture in a second direction comprises moving the movable portion in a direction that is substantially perpendicular to the first direction.

8. A method in accordance with claim 6 wherein said method further comprises coupling the component onto the fixture such that each of a plurality of datum locators is inserted within a respective root cavity defined in the component.

9. A fixture for positioning a gas turbine engine component, said fixture comprising:

a stationary portion comprising at least one stationary datum locator extending outward from said stationary portion; and

a movable portion comprising at least one movable datum locator extending from said movable portion, said at least one movable datum locator is substantially parallel to said at least one stationary datum locator, said movable portion is movable in a direction away from said stationary portion.

10. A fixture in accordance with claim 9 further comprising a step portion positioned adjacent to said at least one stationary datum locator, said step portion configured to support a portion of the component.

11. A fixture in accordance with claim 9 wherein said movable portion is configured to move in a first direction and a second direction.

12. A fixture in accordance with claim 11 wherein said first direction and said second direction are substantially perpendicular to each other.

13. A fixture in accordance with claim 9 wherein said stationary portion comprises at least two datum locators.

14. A fixture in accordance with claim 13 wherein said at least two stationary datum locators and said at least one movable datum locator are substantially aligned.

15. A fixture in accordance with claim 9 wherein at least one datum locator comprises a rib portion.

16. A fixture in accordance with claim 9 wherein at least one datum locator comprises a head portion configured to at least one of receive and complement a corresponding internal feature of the component.

17. A fixture for positioning a gas turbine component including at least one root cavity of the component, said fixture comprising:

a stationary portion comprising at least one stationary datum locator extending outward from said stationary portion, said at least one stationary datum locator configured to fit within the at least one root cavity of the component; and

a movable portion comprising at least one movable datum locator extending from said movable portion, said movable portion is movable in a direction away from said stationary portion.

18. A fixture in accordance with claim 17 further comprising a step portion positioned adjacent to said at least one stationary datum locator, said step portion configured to support a portion of the component.

19. A fixture in accordance with claim 17 wherein said movable portion is configured to move in a first direction and a second direction.

20. A fixture in accordance with claim 17 wherein said stationary portion comprises at least two datum locators.
