Abstract

A method and apparatus for manufacturing a tool for creating composite components. A sheet metal material is secured over a forming tool in an incremental sheet metal forming machine. The sheet metal material is incrementally shaped with a stylus to form a shape for the tool. The tool is removed from the incremental sheet metal forming machine when the shape for the tool is complete. Composite materials on the tool are laid up, wherein the shape of the tool provides a desired shape for a composite component.

First claim

What is claimed is:

1. A method for manufacturing a component, the method comprising:
securing a sheet metal material into an incremental sheet metal forming machine, the incremental sheet metal forming machine comprising a forming tool having a first shape, wherein during securing, a first surface of the sheet metal material contacts the forming tool;
incrementally shaping the sheet metal material with a stylus to form a molding tool for the component, the molding tool having a second shape different than the first shape;
removing the molding tool from the incremental sheet metal forming machine;
forming an inner mold on an inner surface of the molding tool; and
forming an outer mold on an outer surface of the molding tool, wherein the inner mold and the outer mold form a two piece mold for the component.

2. The method of claim 1 further comprising:
forming the component using the two piece mold.

3. The method of claim 1 , wherein the two piece mold is comprised of a material selected from one of fiber glass, carbon, aluminum, steel, and titanium.

4. The method of claim 1 , wherein the two piece mold is comprised of a same material as the component.

5. The method of claim 1 , wherein the method is computer controlled.

6. The method of claim 1 , wherein the component is a composite component.

7. The method of claim 1 , wherein the component is selected from one of a wing panel, a fuselage, and a control surface.
