Abstract

A method for machining a plurality of surfaces of a respective plurality of drawers in an article of furniture includes mounting the article of furniture to a support structure to form a work piece, positioning the work piece on a base of a vertical gantry router in an orientation such that the plurality of surfaces are generally perpendicular to a cutting head of the vertical gantry router, and machining the plurality of surfaces with the vertical gantry router until the plurality of surfaces are substantially flat and substantially coplanar with one another.

First claim

What is claimed is:

1. A method for machining a plurality of surfaces of a respective plurality of drawers of an article of furniture, the method comprising the steps of:
mounting a side of the article of furniture to a support structure to form a work piece;
positioning the work piece on a base of a vertical gantry router in an orientation such that the plurality of surfaces are generally perpendicular to a cutting head of the vertical gantry router;
moving each drawer of the respective plurality of drawers relative to the side of the article of furniture to an extended position such that the plurality of surfaces are generally aligned with one another in a single plane;
fixing each of the drawers in the extended position to define the drawers in fixed, extended positions relative to the side of the article of furniture; and
machining the plurality of surfaces of the drawers in the fixed, extended positions with the vertical gantry router until the plurality of surfaces are substantially flat and substantially coplanar with one another.

2. The method of claim 1 , wherein the step of fixing each of the drawers comprises fixing each of the drawers in the extended position with hot glue.

3. The method of claim 1 , wherein the work piece is secured to the base of the vertical gantry router prior to the machining step.

4. The method of claim 1 , further comprising the step of:
releasing the drawers from the fixed, extended positions after the machining step to allow each of the drawers to move relative to the side of the article of furniture.

5. A method for machining a plurality of surfaces of a respective plurality of drawers of an article of furniture, the method comprising the steps of:
mounting a pair of side plates to opposite sides of the article of furniture to form a work piece, each side plate having a forward edge and a bottom edge that are substantially square to one another;
positioning the work piece on a base of a vertical gantry router, the base being substantially square to a cutting head of the vertical gantry router, the work piece being supported on the base by a bottom surface of each side plate of the pair of side plates;
indexing the work piece with respect to the cutting head;
extending each drawer of the respective plurality of drawers relative to the opposite sides of the article of furniture to an extended position such that each surface of the plurality of surfaces is generally planer with each other surface of the plurality of surfaces;
fixing each drawer of the plurality of drawers in the extended position to define the drawers in fixed, extended positions relative to the opposite sides of the article of furniture;
machining each surface of the plurality of surfaces of the drawers in the fixed, extended positions until each surface is substantially flat and substantially coplanar with each of the other surfaces of the plurality of surfaces.

6. The method of claim 5 , wherein the article of furniture comprises a cabinet configured to be mounted to an aircraft.

7. The method of claim 6 , wherein the opposite sides of the cabinet include a plurality of mounting holes configured to enable the cabinet to be mounted to the aircraft, and wherein the pair of side plates are mounted to the cabinet via the plurality of mounting holes.

8. The method of claim 5 , wherein indexing the work piece with respect to the cutting head comprises pushing the work piece up against a fence of the vertical gantry router, the fence being oriented substantially square and parallel to the cutting head.

9. The method of claim 8 , wherein the fence is disposed at a forward portion of the base and wherein pushing the work piece against the fence comprises pushing the work piece in a forward direction along the base until the work piece contacts and aligns with the fence.

10. The method of claim 8 , wherein the fence is disposed at a rear portion of the base and wherein pushing the work piece against the fence comprises pushing the work piece in a rearward direction along the base until the work piece contacts and aligns with the fence.

11. The method of claim 5 , further comprising the step of securing the side plates to the base.

12. The method of claim 5 , wherein the step of extending each drawer of the plurality of drawers to the extended position comprises extending each drawer until each surface of the plurality of surfaces makes contact with a straight edge placed against the forward edge of each side plate of the pair of side plates.

13. The method of claim 12 , wherein positioning the straight edge against the forward edge of each side plate comprises positioning the straight edge at a location that will intercept each drawer when each drawer is extended.

14. The method of claim 13 , wherein the positioning of the straight edge is repeated until the straight edge has been positioned to intercept each drawer of the plurality of drawers.

15. The method of claim 5 , wherein the step of fixing each drawer of the plurality of drawers in the extended position comprises gluing each drawer in the extended position.

16. The method of claim 15 , wherein the step of fixing each drawer of the plurality of drawers in the extended position comprises using hot glue to fix each drawer in the extended position.

17. The method of claim 5 , wherein further comprising the step of placing a mark on each surface of the plurality of surfaces prior to machining a forward surface of each drawer.

18. The method of claim 17 , wherein the step of placing the mark on each surface of the plurality of surfaces comprises placing ink on each surface.

19. The method of claim 17 , wherein the machining step is performed until the mark on each surface has been machined off.

20. The method of claim 5 , wherein the machining step comprises moving a cutter head of the vertical gantry router along a cutting plane from a first side of the work piece to a second side of the work piece in a first direction, moving the cutter head in a second direction in the cutting plane by an amount equal to a width of the cutter head, the second direction being substantially perpendicular to the first direction, and then moving the cutter head in the cutting plane in a third direction from the second side of the work piece to the first side of the work piece, the third direction being substantially opposite to the first direction.
