Abstract
A tool for contouring an airfoil comprises a main body that includes a locator portion and an upper portion. The locator portion includes an engagement surface and the engagement surface is sized and configured to engage an airfoil. The upper portion includes an edge slot sized and configured for placement of an edge of the airfoil into the slot. An abrasive material is applied to the sides of the edge slot. The upper portion and the locator portion are together sized and shaped so that when the edge of the airfoil is disposed in the edge slot and the engagement surface of the locator portion is simultaneously pressed against the airfoil, engagement of the abrasive material with the edge of the airfoil is effective to contour the edge of the airfoil to a preselected and desired shape.
Claims16
A tool for contouring an edge of an airfoil, the tool comprising:
- a main body, comprising:
- an edge slot, wherein the edge slot is configured to be positioned on an edge of an airfoil;
- and
- an engagement surface configured to engage at least one surface of the airfoil when the edge slot receives the edge of the airfoil to orient the edge slot with respect to the edge of the airfoil;
- wherein the tool is one of a set of tools;
- where the set of tools comprises a first tool, a second tool, and a third tool, wherein the first tool is configured to remove erosion from the edge of the airfoil and the second tool is configured to remove high points from the airfoil.
A set of tools for contouring an edge of an airfoil, the set of tools comprising:
- a first tool, the first tool having a main body, the main body comprising:
- an edge slot, wherein the edge slot is configured to be positioned on an edge of an airfoil;
- and
- an engagement surface configured to engage at least one surface of the airfoil when the edge slot receives the edge of the airfoil to orient the edge slot with respect to the edge of the airfoil;
- wherein the first tool is configured to remove erosion from the edge of the airfoil, a second tool configured to remove high points from the airfoil.
