Abstract

A web interface allows users to automatically nest equipment parts. Necessary material and data information are generated and input to a CAD/CAM program that places the parts on one or more sheets of material. A laser program is also generated for laser to cut the parts according to the arrangement.

Claims

1. A method for automatic sheet nesting of equipment parts, comprising:

receiving data associated with one or more parts to nest over a network;

sorting the parts by material type;

determining optimal arrangement of the parts on a sheet of material for each material type; and

generating a laser program to cut the parts.

2. The method of claim 1, wherein the sorting further includes selecting suitable sheet material for the parts.

3. The method of claim 1, wherein the sorting further includes creating separate computer file system directory for each material type.

4. The method of claim 1, wherein the determining further includes:

determining if anyone of the parts can fit on a precut material, and if a part can fit on a precut material,

excluding the sorted part from placing on the sheet of material.

5. The method of claim 1, wherein the method further includes:

generating a list of parts that are arranged on a sheet of material.

6. The method of claim 5, wherein the method further includes:

allowing a user to modify the arrangement by entering one or more parameters that affect the arrangement.

7. The method of claim 6, wherein the one or more parameters include tab spacing.

8. The method of claim 6, wherein the one or more parameters include skeleton parameters.

9. The method of claim 6, wherein the one or more parameters include work zone size.

10. The method of claim 6, wherein the one or more parameters include clamp number.

11. The method of claim 6, wherein the one or more parameters include clamp location.

12. The method of claim 1, further including:

transmitting the laser program to a laser to initiate cutting.

13. The method of claim 1, further including:

receiving an equipment identifier associated with the equipment for nesting; and

identifying parts in equipment for nesting, the equipment identified by the equipment identifier.

14. The method of claim 1, wherein the receiving includes:

receiving data associated with the one or more parts for nesting via a user interface accessed over a computer network.

15. The method of claim 1, further including:

receiving data associated with the one or more parts for nesting via a web interface.

16. A method for automatic sheet nesting of equipment part, comprising:

providing a user interface over a communication network;

receiving via the user interface over the network, one or more parts data associated with one or more parts to nest;

sorting the one or more parts by material type;

transmitting information associated with the one or more parts to optimally arrange the one or more parts on one or more sheets of material;

receiving arranged information about the parts;

generating a laser program to cut the parts according to the arranged information; and

displaying the arranged information on the user interface.

17. The method of claim 16, wherein the user interface includes a web enabled interface.

18. A computerized system for nesting equipment parts, comprising:

user interface module for entering data associated with one or more parts to nest;

a setup module that receives the data from the user interface module, associates one or more parts with one or more sheets of material, the setup module generating one or more data and command files for nesting;

a program module in response to receiving the one or more data and command files, generating an optimal arrangement of the one or more parts on one or more sheets of material, the program modules further generating one or more text commands for laser for cutting the one or more parts according to the optimal arrangement;

a post processing module, in response to receiving the one or more text commands, operative to convert the text commands into laser commands.

19. The system of claim 18, wherein the user interface module include a web-enabled user interface.

20. A program storage device readable by machine, tangibly embodying a program of instructions executable by the machine to perform method steps of automatic sheet nesting of equipment part, comprising:

providing a user interface over a communication network;

receiving via the user interface over the network, one or more parts data associated with one or more parts to nest;

sorting the one or more parts by material type;

transmitting information associated with the one or more parts to optimally arrange the one or more parts on one or more sheets of material;

receiving arranged information about the parts;

generating a laser program to cut the parts according to the arranged information; and

displaying the arranged information on the user interface.
