Abstract

System and method for utilizing drawing specifications for use in motion control. Elements in a drawing specification may be automatically identified. The drawing specification may include one or more drawings, digital files, AutoCAD drafting files, and/or drawing specifications. Code may be automatically generated based on the one or more elements in accordance with a schema, and may include instructions in a data representation language, e.g., a markup language such as HTML, XML, etc. The automatically generated code may include move operations, e.g., arc, contour, line, raise, lower, halt, begin, etc., with associated parameters, e.g., move constraints, digital outputs, position compares, etc. The schema may include one or more blocks, each associated with a portion of the drawing specification, one or more elements, each associated with a block, one or more move operations, each associated with an element, and one or more parameters, each associated with a move operation.

Claims

1. A method for utilizing drawing specifications for use in motion control, comprising:

automatically identifying one or more elements in a drawing specification; and

automatically generating code based on the one or more elements in accordance with a schema, wherein the code comprises instructions in a data representation language, and wherein the code is usable for implementing motion control.

2. The method of claim 1, wherein said automatically generating code based on the one or more elements in accordance with a schema comprises:

generating one or more blocks, each corresponding to a respective portion of the drawing specification;

wherein each of the one or more blocks comprises a respective one or more elements of the one or more elements; and

wherein each of the respective one or more elements comprises one or more associated move operations.

3. The method of claim 2,

wherein each of the one or more move operations comprises one or more associated parameters.

4. The method of claim 2,

wherein each of the one or more respective portions comprises one or more of:

a drawing; and

a digital drafting file.

5. The method of claim 1,

wherein the drawing specification comprises one or more digital files.

6. The method of claim 1,

wherein the drawing specification comprises one or more AutoCAD digital drafting files.

7. The method of claim 1,

wherein the drawing specification comprises one or more drawings.

8. The method of claim 1,

wherein the drawing specification comprises one or more drawing specifications.

9. The method of claim 1, wherein said automatically generating code comprises:

automatically generating one or more move operations.

10. The method of claim 9,

wherein the one or more move operations comprise one or more of:

a line move operation;

an arc move operation;

a contour move operation;

a begin move operation;

a halt move operation;

a raise move operation; and

a lower move operation.

11. The method of claim 9,

wherein the one or more move operations each have one or more associated parameters.

12. The method of claim 11,

wherein the one or more associated parameters comprise one or more of:

one or more move constraints;

one or more digital outputs; and

one or more position compares.

13. The method of claim 1,

wherein the data representation language comprises a markup language.

14. The method of claim 1,

wherein the data representation language comprises eXtensible Markup Language (XML).

15. The method of claim 1,

wherein the generated code comprises instructions usable to control a motion control device, wherein the motion control device is operable to perform one or more of:

drawing on one or more materials;

tracing one or more materials;

etching one or more materials; and

cutting one or more materials.

16. The method of claim 15,

wherein the one or more materials comprise one or more of:

metal;

wood;

polymer;

one or more chemical compounds; and

one or more chemical elements.

17. The method of claim 1,

wherein the one or more elements comprise one or more of:

one or more lines;

one or more polygons;

one or more arcs;

one or more splines;

one or more alphanumeric characters in one or more associated fonts;

one or more ellipses; and

one or more clouds.

18. The method of claim 1,

wherein the one or more elements compose one or more shapes, wherein each shape of the one or more shapes comprises a subset of the one or more elements.

19. The method of claim 1,

wherein the one or more elements compose one or more complex elements, wherein each complex element of the one or more complex elements comprises a subset of the one or more elements.

20. The method of claim 1,

wherein said automatically identifying the one or more of elements and said automatically generating code is performed by one or more of:

one or more graphical programs, wherein each of the one or more graphical programs comprises a plurality of interconnected nodes that visually indicate functionality of the graphical program; and

one or more text-based programs.

21. The method of claim 1, the method further comprising:

displaying a visual representation of the generated code in a graphical user interface (GUI) displayed on a display device of a computer system.

22. The method of claim 1, the method further comprising:

receiving user input to a GUI invoking one or more of said automatically identifying the one or more elements and said automatically generating code.

23. The method of claim 1;

the method further comprising;

receiving user input to a GUI specifying modification of the generated code; and

automatically modifying the generated code based on the user input.

24. The method of claim 1, the method further comprising:

automatically inserting move operations into the generated code; and

receiving user input to a GUI displayed on a display device of a computer system, wherein the GUI indicates the move operations, and wherein the user input specifies enabling or disabling display of the move operations.

25. A system for utilizing drawing specifications for use in motion control, comprising:

a processor; and

a memory coupled to the processor, comprising instructions executable by the processor to;

automatically identify one or more elements in a drawing specification; and

automatically generate code based on the one or more elements in accordance with a schema, wherein the code comprises instructions in a data representation language, and wherein the code is usable for implementing motion control.

26. A computer-accessible memory medium for utilizing drawing specifications for use in motion control, comprising instructions executable by a processor to implement:

automatically identifying one or more elements in a drawing specification; and

automatically generating code based on the one or more elements in accordance with a schema, wherein the code comprises instructions in a data representation language, and wherein the code is usable for implementing motion control.

27. A system for utilizing drawing specifications for use in motion control, comprising:
