Abstract

A system, method, and computer program for monitoring a machine cycle, comprising the steps of tracking an elapsed cumulative measure; comparing said elapsed cumulative measure with a cycle interrupt interval; interrupting a machining cycle at said cycle interrupt interval; and performing a local return to a defined position upon said interrupting step and appropriate means and computer-readable instructions.

Claims

1. A method of monitoring a machine cycle, comprising the steps of:

tracking an elapsed cumulative measure;

comparing said elapsed cumulative measure with a cycle interrupt interval;

interrupting a machining cycle at said cycle interrupt interval; and

performing a local return to a defined position upon said interrupting step.

2. The method of claim 1, wherein said elapsed cumulative measure is a machine time.

3. The method of claim 1, wherein said elapsed cumulative measure is cutting distance.

4. The method of claim 1, wherein said cycle interrupt interval is an automatic local return interval.

5. The method of claim 1, wherein said cycle interrupt interval is one of an action and an occurrence.

6. The method of claim 1, wherein said performing step occurs at an automatic local return time.

7. The method of claim 1, wherein said performing step occurs at an automatic local return distance.

8. The method of claim 1, wherein said defined position is one of a user defined position and an automatically defined position.

9. The method of claim 1, further comprising the step of updating and adjusting said cycle interrupt interval.

10. The method of claim 1, further comprising the step of updating said elapsed cumulative measure.

11. The method of claim 1, further comprising the step of analyzing a plurality of processor generated motions.

12. A computer-program product tangibly embodied in a machine readable medium to perform method of monitoring a machine cycle, comprising:

instructions for tracking an elapsed cumulative measure;

instructions for comparing said elapsed cumulative measure with a cycle interrupt interval;

instructions for interrupting a machining cycle at said cycle interrupt interval; and

instructions for performing a local return to a defined position upon said interrupting step.

13. The computer-program product of claim 12, wherein said elapsed cumulative measure is a machine time.

14. The computer-program product of claim 12, wherein said elapsed cumulative measure is cutting distance.

15. The computer-program product of claim 12, wherein said cycle interrupt interval is an automatic local return interval.

16. The computer-program product of claim 12, wherein said cycle interrupt interval is one of an action and an occurrence.

17. The computer-program product of claim 12, wherein said performing instructions occur at an automatic local return time.

18. The computer-program product of claim 12, wherein said performing instructions occur at an automatic local return distance.

19. The computer-program product of claim 12, wherein said defined position is one of a user defined position and an automatically defined position.

20. The computer-program product of claim 12, further comprising the instructions of updating and adjusting said cycle interrupt interval.

21. The computer-program product of claim 12, further comprising the instructions of updating said elapsed cumulative measure.

22. The computer-program product of claim 12, further comprising the instructions of analyzing a plurality of processor generated motions.

23. A data processing system having at least a processor and accessible memory to implement a method of monitoring a machine cycle, comprising:

means for tracking an elapsed cumulative measure;

means for comparing said elapsed cumulative measure with a cycle interrupt interval;

means for interrupting a machining cycle at said cycle interrupt interval; and

means for performing a local return to a defined position upon said interrupting step.
