CAM/Cpk CNOMO multistep parameters

General category

  • Name: type the name of the inspection.

  • Barcode identifier: it identifies the inspection. If left blank, the identifier corresponds to the inspection name.

  • Strategy: select the tool strategy “Multistep”.

  • Number of samples: type the number of results to do.

    The maximum number of samples is 99.

  • Measurement device type: STbench is the only measuring device available for this test strategy.

  • Measurement device S/N: type the serial number of the measuring device connected to the device.

  • STbench channel: select the STbench channel to use to do the test. The available options are:

    • Manual selection.

    • Number of the STbench channel (from 1 to 8).

      The test must be performed on an external transducer, not on the STbench brakes

  • Transducer S/N: type the serial number of the transducer linked to the measuring device connected to the device.

  • Filter frequency: type the value of the filter frequency. The allowed range is from 100 to 2000 Hz. The default value is 500 Hz.

  • Tightening direction: from the drop down list select the tightening direction. The available items are Clockwise and Counterclockwise.

  • Minimum CAM Torque: type the minimum value of the CAM index for the torque.

    Minimum CAM Torque ranges from 0 to 9999.

  • Minimum Cpk Torque: type the minimum value of the Cpk index for the torque.

    Minimum Cpk Torque ranges from 0 to 9999.

  • Minimum CAM angle: type the minimum value of the CAM index for the angle.

    Minimum CAM Angle ranges from 0 to 9999.

  • Minimum Cpk angle: type the minimum value of the Cpk index for the angle.

    Minimum Cpk Angle ranges from 0 to 9999.

  • Measure delay time: type the value of the measure delay time.

    During the measure delay time the torque trace is not analyzed and the click-point is not detected.

    The measure delay time ranges from 0.0 s to 5.0 s.

  • Cycle start: the default value is managed by the measuring device and it is indicated as Automatic value. It is possible to type the cycle start value.

    It must be higher than the transducer Minimum load and equal/lower than the Final angle monitoring torque.

    If the cycle start is set to zero, the device gives automatically a Cycle Start equal to the transducer Minimum load.

  • Final angle monitoring torque: type the final angle monitoring torque value.

  • Unit of measurement: select the unit of measurement to use.

Steps category

  • Step type: select between the following:

    • Tightening.

    • Loosening.

  • Check type: select between the following:

    • Torque.

    • Angle.

  • Control mode: select how to define the limits of the selected variable (torque or angle). The options are: Min/Max and Target/tolerance.

    Minimum angle/torque and Maximum angle/torque are automatically defined according to the Angle/Torque tolerance specified.

  • Minimum torque/angle: type the minimum value of the torque/angle. This parameter is available if Control mode is set to Min/Max.

  • Maximum torque/angle: type the maximum value of thetorque/ angle. This parameter is available if Control mode is set to Min/Max.

  • Target torque/angle: type the value of the target torque/angle. This parameter is available if the Target/Tolerance option of the Control mode is selected.

  • Torque/angle tolerance: type the value of the tolerance of the torque/angle. This parameter is available if Control mode is set to Target/Tolerance.

  • End cycle time: type the value of the end cycle time.

    The “quick programming” test stops when the torque continues to be applied but it is under the Cycle complete for a time longer than the End cycle time.

    The end cycle time ranges from 0.1 s to 5.0 s.

  • Used for result: select the Used for result check box for using the specific step for the final result.

  • Measure torque at: select one of the following options:

    • Torque peak

    • Angle peak
