Abstract

A computer-implemented method for rapidly forming a vehicle body model includes identifying a vehicle design using a computer. Sectioning data is determined by sectioning the vehicle design into multiple virtual sections using a design program implemented on the computer. The sectioning data is used by a machine to form multiple modeling sections that correspond to the multiple virtual sections. The multiple modeling sections are nested together to form the vehicle body model. The multiple modeling sections are fixed together once the vehicle body model is formed.

Claims

1. A computer-implemented method for rapidly forming a vehicle body model, the method comprising:

(a) identifying a vehicle design using a computer;

(b) determining sectioning data by sectioning the vehicle design into multiple virtual sections using a design program implemented on the computer;

(c) determining glue channel location information using the design program;

(d) providing a block of modeling material to a machine configured for machining the block;

(e) the machine using the sectioning data determined in step (b) to machine the block into a modeling section corresponding to at least one of the virtual sections;

(f) repeating steps (d) and (e) for each of the virtual sections; and

(g) assembling the modeling sections formed in steps (e) and (f) to form the vehicle body model.

2. The method of claim 1, wherein step (e) includes the machine using the glue channel location information in forming a glue hole in the modeling section.

3. The method of claim 2, wherein the glue hole extends from an upper nesting surface to a lower nesting surface.

4. The method of claim 3, wherein step (g) includes nesting a first modeling section with a second modeling section wherein the first modeling section includes a first glue hole and the second modeling section includes a second glue hole, the first and second glue holes being aligned to form at least part of a glue channel.

5. The method of claim 4, wherein step (g) includes providing an adhesive material through the glue channel.

6. A computer-implemented method for rapidly forming a vehicle body model, the method comprising:

(a) identifying a vehicle design using a computer;

(b) determining sectioning data by sectioning the vehicle design into multiple virtual sections using a design program implemented on the computer;

(c) determining dowel hole location information using the design program;

(d) providing a block of modeling material to a machine configured for machining the block;

(e) the machine using the sectioning data determined in step (b) to machine the block into a modeling section corresponding to at least one of the virtual sections;

(f) repeating steps (d) and (e) for each of the virtual sections; and

(g) assembling the modeling sections formed in step (e) to form the vehicle body model.

7. The method of claim 6, wherein step (e) includes the machine using the dowel hole location information in forming a dowel hole in the modeling section.

8. The method of claim 7, wherein step (g) includes nesting a first modeling section with a second modeling section wherein the first modeling section includes a first dowel hole and the second modeling section includes a second dowel hole, the first and second dowel holes being aligned.

9. The method of claim 8, wherein step (g) includes providing a dowel in the first and second dowel holes such that the dowel straddles the first and second dowel holes.

10. A computer-implemented method for rapidly forming a vehicle body model, the method comprising:

identifying a vehicle design using a computer;

determining sectioning data by sectioning the vehicle design into multiple virtual sections using a design program implemented on the computer and determining glue channel location information using the design program implemented on the computer, the sectioning data and the glue channel location information being used by a machine to form multiple modeling sections that correspond to the multiple virtual sections;

nesting the multiple modeling sections together to form the vehicle body model; and

fixing the multiple modeling sections together once the vehicle body model is formed.

11. The method of claim 10 comprising using the glue channel location information in forming a glue hole in the modeling sections.

12. The method of claim 11, wherein the glue hole extends from an upper nesting surface to a lower nesting surface of the modeling sections.

13. The method of claim 12 comprising nesting a first modeling section with a second modeling section wherein the first modeling section includes a first glue hole and the second modeling section includes a second glue hole, the first and second glue holes being aligned to form at least part of a glue channel.

14. The method of claim 13 further comprising providing an adhesive material through the glue channel.

15. The method of claim 10 further comprising determining dowel hole location information using the design program.

16. The method of claim 15 comprising using the dowel hole location information in forming a dowel hole in the modeling section.
