Abstract

A vane tip machining fixture assembly includes a first clamp ring mountable to a fixture, the first clamp ring includes a rigid back ring mounted to a resilient ring.

First claim

What is claimed is:

1 . An airfoil tip machining fixture assembly, comprising:
a fixture; and a first clamp ring mountable to said fixture, said first clamp ring includes a rigid back ring mounted to a resilient ring.

2 . The assembly as recited in claim 1 , wherein said resilient ring is manufactured of rubber.

3 . The assembly as recited in claim 1 , wherein said resilient ring is mountable toward said fixture.

4 . The assembly as recited in claim 1 , wherein said first clamp ring mountable to said fixture with a multiple of fasteners.

5 . The assembly as recited in claim 4 , wherein said multiple of fasteners are angled with respect to an engine central longitudinal axis.

6 . The assembly as recited in claim 5 , further comprising a second clamp ring mountable to said first clamp ring with a multiple of fasteners.

7 . The assembly as recited in claim 6 , wherein said multiple of fasteners are angled with respect to said engine central longitudinal axis.

8 . The assembly as recited in claim 7 , further comprising a third clamp ring mountable to said second clamp ring with a multiple of fasteners.

9 . The assembly as recited in claim 8 , wherein said multiple of fasteners are angled with respect to said engine central longitudinal axis.

10 . A method of machining tips of a multiple of cantilevered mounted stator vane airfoils of a gas turbine engine comprising:
resiliently biasing the multiple of cantilevered mounted stator vane airfoils with a clamp ring.

11 . The method as recited in claim 10 , further comprising:
fastening the clamp ring to a fixture.

12 . The method as recited in claim 11 , further comprising:
fastening the clamp ring to a fixture with a multiple of fasteners, the multiple of fasteners angled with respect to an engine central longitudinal axis.

13 . The method as recited in claim 12 , further comprising:
fastening a second clamp ring to the clamp ring.

14 . The method as recited in claim 13 , further comprising:
fastening the second clamp ring to the clamp ring with a multiple of fasteners, the multiple of fasteners angled with respect to the engine central longitudinal axis.

15 . The method as recited in claim 10 , further comprising:
machining the tips of the multiple of cantilevered mounted stator vane airfoils with respect to an engine central longitudinal axis.

16 . The method as recited in claim 10 , further comprising:
resiliently biasing the multiple of cantilevered mounted stator vane airfoils in each of a multiple of stages with a respective clamp ring.

17 . The method as recited in claim 10 , further comprising:
resiliently biasing the multiple of cantilevered mounted stator vane airfoils in each of a multiple of stages with a respective clamp ring, a resilient ring of the respective clamp ring directed toward a fixture.
