Template for evaluating parts and method of using same
View Patent ↗A template for evaluating a part, comprising: a surface having a shape corresponding to the part; and at least one element on the surface corresponding to a desired location of a feature on the part. A method of evaluating a part, comprising the steps of: providing a template having a shape corresponding to the part and at least one element thereon corresponding to a desired location on the part; associating the template with the part; and using the element to determine whether the feature is at the desired location.
1. A template for evaluating gas turbine airfoil, comprising:
an interior surface having a shape corresponding to the airfoil;
an exterior surface; and
at least one element on said external surface corresponding to a desired location of a feature on said part;
wherein said at least one element comprises at least one scribe line to assists a user to determine whether said feature is at said desired location.
2. The template of claim 1 , further comprising at least one protuberance to contact said airfoil; wherein said at least one protuberance is integrally formed with said interior surface.
3. The template of claim 2 , wherein said template has at least five protuberances.
4. The template of claim 3 , wherein said template has six protuberances.
5. The template of claim 1 , wherein said element comprises printed indicia.
6. The template of claim 1 , wherein said template further comprises a depressed area; and wherein said depressed area comprises an element that is scallop shaped.
7. A method of evaluating gas turbine airfoil, comprising the steps of:
providing a template having a shape corresponding to said airfoil and at least one scribe line element thereon corresponding to a desired location of a feature on said airfoil;
associating said template with said airfoil; and
using said at least one scribe line element to determine whether said feature is at said desired location.
8. The method of claim 7 , wherein said associating step comprises placing said template against said airfoil.
9. The method of claim 8 , wherein said template further comprises at least one integrally formed protuberance to contact said part.
10. The method of claim 9 , wherein said template has at least five protuberances.
11. The method of claim 10 , wherein said template has six protuberances.
12. The method of claim 7 , wherein said determining step includes a step of viewing through said template.
13. The method of claim 7 , wherein said element comprises printed indicia.
14. The method of claim 7 , wherein said template comprises a depressed area; and
wherein said depressed area comprises an element that is scallop shaped.
15. The template of claim 1 wherein said at least one element is noncircular.
16. The template of claim 15 wherein said at least one element comprises a first scribe line corresponding to a minimum tolerance of the desired location of the feature and a second scribe line corresponding in a maximum tolerance of the desired location of the feature.
17. The template of claim 1 wherein said template is made of resin using a sterolithography apparatus.
