The CEI TMAC System protects machine tools, tooling, and workpieces by detecting worn & broken tooling on CNC machine tools in real time. Adaptive control machining can reduce part cycle times and improve tool life. Coolant and spindle speed monitoring is also available.

1. Advanced Tool Condition Monitoring and Control

5. Measures the horsepower of a new tool during a cut

6. Determines whether a tool is worn or broken by comparing the cutting horsepower to user programmed limits

8. Dual Range Transducer When the transducer is set to the full range of the motor the effect of a small tool is not as easily determined. Drill cutting With the dual range transducer set at a smaller range the effect of the tool is much easier to determine Drill cutting

9. Measuring Horsepower The Tool Monitor separates the cutting horsepower from the horsepower required to idle the motor under no load Start Signal Actual Cutting HP Learned HP Horsepower Idle HP Time This technique eliminates any effect from the spindle on the measured horsepower

10. Using Horsepower Our tool monitoring works on the simple concept that the horsepower used by a tool increases as it gets dull EXTREME Horsepower WEAR Part# 1 10 15 20 25 28 29

12. Adaptive control

13. Coolant Flow and Spindle Speed Monitoring

14. Network connectivity

15. Data logging

17. Handles all communications to the CNC control

18. Handles all analog sensor inputs, all digital inputs and outputs

19. It can run standalone without any PC connected

21. Electrically sums the current and voltage reference

22. Provides a 0-10 Volt signal respective of the horsepower

24. Allows a constant 30 second window of all monitoring and adaptive control

25. Can run on a customer supplied PC

26. Stores data for later analyses with TMS Viewer

28. The user sets limits for Extreme, Wear and Undercut for each tool (any combination)

29. The CNC starts the system monitoring for each tool

32. For a tap (Okuma only) unwind out of material

35. The range of allowable override is set

36. (0-255% for most controls)

37. Adaptive control is started by the CNC and the feedrate override control is switched to the TMAC

40. The first hole is drilled without using adaptive control

41. Red represents tool breakage

42. The second cycle uses adaptive control to protect your drill

45. The switch to each set of limits occurs by specified time after the first call from the CNC

46. In the learn mode, each time segment learns a separate peak horsepower

47. Any number of segments can be used for each tool

50. Multiple holes with the same drill but varying material thicknesses

51. Deep hole drilling

52. Turning applications with variations in diameter

53. Contour milling

55. Allows horsepower limits based on the rate of change of a cut

56. Each slope can be set in the positive or negative direction

58. The white line shows actual cutting horsepower

59. The red and yellow lines are the extreme and wear limits respectively

60. The Blue line is the under-cut limit8/6/2009 Caron Engineering TMS System7 24

61. Using Slope and Normal This example shows that using time slicing, normal monitoring and slope monitoring can be used during a cut Normal Monitoring Slope Monitoring

63. The user sets the minimum flow/pressure allowed per tool

64. If the coolant flow/pressure drops below this level, an alarm is generated

65. All coolant flow/pressure is also graphed and can be reviewed with TMS Viewer

68. All monitoring data can be saved and later viewed with TMS Viewer

71. Allows the user to create separate data files
