Abstract

The present invention provides a method and apparatus for use in manufacturing a composite part includes molding a composite part on a lay-up tool, machining a sacrificial portion of a first surface for securing a first hardware device with the composite part while the part is on the lay-up tool and cutting the part forming a peripheral edge while the part is on the lay-up tool. The method can further include positioning the first hardware device in contact with a machined interface of the composite part and machining the part including drilling a plurality of positioning holes through the hardware device and the part while the part is on the lay-up tool. The machining can include machining the sacrificial portion creating a machined interface and positioning the hardware device on the machined interface.

Claims (46)

1. A method for use in manufacturing a composite part, comprising:

forming a composite part on a lay-up tool;

machining a sacrificial portion of at least one portion of a first surface of the composite part to provide a machined interface while the composite part is on the lay-up tool; and

cutting the composite part forming a peripheral edge while the composite part is on the lay-up tool.

2. The method as claimed in claim 1 , further comprising:

positioning a first hardware device in contact with the composite part; and

drilling a plurality of positioning holes through the first hardware device and the composite part while the composite part is still on the lay-up tool.

3. The method as claimed in claim 2 ,

wherein the positioning includes positioning the first hardware device on the at least one machined interface of the first surface.

4. The method as claimed in claim 1 , further comprising:

positioning a first hardware device over the machined interface.

5. A method for use in manufacturing a composite part, comprising:

A forming a composite part on a lay-up tool including building up at least one portion of a first surface to a level greater than a surrounding portion of the first surface providing a sacrificial portion;

machining at least a portion of the sacrificial portion while the composite part is on the lay-up tool; and

cutting to composite part forming a peripheral edge while the composite part is on the lay-up tool.

6. The method as claimed in claim 5 , farther comprises:

probing the sacrificial portion of the first surface prior to the step of machining; and

determining a depth at which to machine the sacrificial portion of the first surface prior to the step of machining.

7. The method as claimed in claim 6 , further comprising:

controlling the machining according to a data set having a digital definition of the composite part.

8. The method as claimed in claim 7 , wherein the machining further comprising:

guiding a machining device based on the data set to the sacrificial portion of the first surface and guiding the machining device based on the data set to machine the sacrificial portion to provide a machined interface;

guiding a drill based on the data set to a plurality of predefined points of the machined interface and guiding the drill to drill at each of the predefined points; and

wherein the cutting includes guiding a cutter based on the data set on a predetermined path cutting the peripheral edge.

9. A method for use in fabricating and assembling a composite part, comprising:

molding a composite part on a lay-up tool having a desired shape;

machining a sacrificial portion of a first surface creating a machined interface while the composite part is still on the lay-up tool;

positioning a first hardware device in contact with the machined interface of the first surface while the composite part is still on the lay-up tool; and

drilling a plurality of securing holes into the first hardware device and the composite part while the composite part is still on the lay-up tool.

10. The method as claimed in claim 9 , further comprising:

cutting the composite part while the composite part is still on the lay-up tool.

11. The method as claimed in claim 10 , wherein the cutting includes guiding a cutter on a predefined path ad cutting the composite part.

12. The method as claimed in claim 11 , wherein the guiding the cutter includes guiding the cutter with a controller operating a machine control program incorporating a data set on the predefined path around a facing surface of the lay-up tool, with the cutter cutting in a sacrificial material in the facing surface of the lay-up tool and cutting a peripheral edge of the composite part.

13. The method as claimed in claim 9 , wherein the machining and the drilling include:

guiding a machining device, with a controller operating a machine control program incorporating a data set, over the sacrificial portion of the first surface; and

guiding a drill, with the controller, to predefined positions over the first hardware device and the composite part.

14. The method as claimed in claim 9 , further comprising:

drilling positioning holes in the machined interface prior to the positioning of the first hardware device; and

wherein the positioning the first hardware device includes securing the first hardware device with the composite part through the positioning holes.

15. The method as claimed in claim 14 , further comprising:

further securing the first hardware device with the composite part through at least one of the plurality of drilled securing holes;

unsecuring the first hardware device at the positioning holes; and

drilling the positioning holes to a size equal with the plurality of securing holes.

16. The method as claimed in claim 9 , further comprising:

verifying a location of the lay-up tool prior to the machining and the drilling; and

probing a position of the sacrificial portion of the first surface of the composite part prior to the machining and the drilling.
