Abstract

Color is added to the standard video display (18) of a computer numerical control system for controlling the operation of a machine tool (10) in the performance of specified operations with respect to a workpiece. Color assignment records (62) are included in the machine setup data (MSD) source file (54) for implementing background color, reverse video color, forms character color, data character color, errors and/or alarm color, operator required response color, and high-lite color. The MSD source file (54) is processed to generate a binary MSD file (56) which is then read into the numerical control basic (NC) software (24) which operates to generate both text and graphic displays. The original or default color assignments may be dynamically modified or changed through an MSD file editor (58). Additionally, the background color and data character color are programmed to change to other colors to bring the operator'"'"'s attention to an error or alarm condition through the machine control logic (MCL) (28) which generates calls through a software interface (26) to the NC software (24).

Claims

1. A method of enhancing the visual display of a computer numerical control machining system by the addition of color thereto, comprising the steps of:

(a) generating and entering color assignment records in a stored machine set up data (MSD) source file containing data for the generation of a visual display of predetermined information relating to system operation;

(b) processing said records of said source file and generating therefrom an MSD binary file;

(c) transferring color assignment data from said MSD binary file to a display control system;

(d) generating a visual display in color in response to signals generated by processing said display control file; and

(e) modifying the color assignment data in accordance with changing conditions of the numerical control system.

2. The method as defined by claim 1 and additionally including the step of modifying said MSD binary files by an operator on demand prior to said step of transferring.

3. The method as defined by claim 2 and additionally including the step of modifying said MSD binary file by entering new color assignment records into a file editor coupled to said MSD binary file, said editor operating to generate modified usable stored data files which are thereafter entered into the MSD binary file and thereafter transferred to said display control system.

4. The method as defined by claim 1 wherein the step of modifying color assignment data is in response to predetermined detected operating conditions of the machining system.

5. The method of claim 4 wherein said machining system operates in accordance with an executed routine of a machine control logic program and wherein said step of modifying said color assignment data comprises modifying color assignment data by system operation error routines of the machines control logic program.

6. The method as defined by claim 4 and wherein said step of generating and entering color assignment records includes color assignment records for background color, reverse video color, forms character color, data character color, errors and alarms color, operated required response color and high-lite color.

7. The method as defined by claim 6 and additionally including the step of modifying said color assignments on demand by an operator.

8. The method as defined by claim 7 and wherein said step of generating and entering color assignment records further comprises establishing specific default colors for the data color, the background color, reverse video color and high-lite color.

9. The method as defined by claim 8 and additionally including the step of selectively overriding the default data character color with the forms character color, the error and alarm character color and the operator required response color and thereafter reverting back to the default color assignment of the data character color.

10. The method as defined by claim 6 and additionally including the step of changing background color and data character color in response to a predetermined sensed system operating condition and thereafter reverting back to their previously assigned colors when said condition is no longer present.

11. The method as defined by claim 10 wherein said system operates in accordance with a plurality of stored computer programs and data files including the numerical control logic software and the machine control logic program and being coupled together through a software interface, and

wherein said step of changing the background color and data character color in response to sensed system operating condition comprises executing calls from the machine control logic software to the display control file included in the numerical control logic program through said interface.

12. A system for adding color to the video display of a computer numerical control machining system, comprising:

a first data file containing color assignment records for the generation of color displays of predetermined information relating to system operation;

means for processing said records of said first data file and generating therefrom a second data file in machine usable form;

means for transferring color assignment record data from said second data file to a display control system;

means for generating a visual display in color in response to said video display producing signals; and

means for modifying the color assignment data in accordance with changing conditions of the computer numerical control machining system.

13. The method as defined by claim 12 and additionally including means for modifying said second data file by an operator.

14. The system as defined by claim 12 wherein said means for modifying color assignment data is adapted to respond to predetermined sensed operating conditions of the machining system.

15. The method of claim 14 wherein said machining system operates in accordance with executed routines of a machine control logic program and wherein said means for modifying said color assignment data comprises modifying color assignment data by system operation error routines of the machine control logic program.

16. The system as defined by claim 12 wherein said first data file comprises a machine setup data source file and said second data file comprises a machine setup data binary file and additionally including a file editor coupled to said machine setup data binary file, said file editor being operable to generate modified usable stored data files.

17. The system as defined by claim 12 and wherein color assignment records include color assignment records for background color, reverse video color, forms character color, data character color, errors and alarms color, operated required response color and high-lite color.

18. The system as defined by claim 17 and wherein said color assignment records for the data color, the background color, reverse video color and high-lite color are defined in predetermined default colors.

19. The system as defined by claim 18 and additionally including means for selectively overriding the default data character color with the forms character color, the error and alarm character color and the operator required response color and thereafter reverting back to the default color assignment of the default data character color.

20. The system as defined by claim 12 and additionally including means for changing background color and data character color in response to a predetermined sensed system operating condition and thereafter reverting back to their previously assigned colors when said condition is no longer present.

21. The system as defined by claim 20 wherein said system further comprises a plurality of stored computer programs and data files including the numerical control logic software and the machine control logic program and being coupled together through a software interface, and

wherein said means for changing the background color and data character color in response to sensed system operating condition includes means for executing calls from the machine control logic software to the numerical control logic program through said interface.
