7.3 Probing Cycles

positioningFeedRate_Normally - set to the feedrate the control will use while normally positioning the probe around the part positioningFeedRate_FirstTouch - set to the feedrate the control will use while making its initial touch to find the surface it is measuring.

dwellTimeAfterProbeActive - for wireless probes, set to the time to wait after the probe is turned on before attempting a probe move, as recommended by the probe manufacturer.

updateTloOrWorkOffsetZAxis - select whether to update the values for the Tool Length Offset (TLO) or the Workpiece Offset (WorkOffset).

Spindle Probe Calibration Cycle

This is used to set the effective probe stylus diameter and set the compensation factor for any run-out of the probe stylus.

You need to have already configured the spindle probe settings per the previous section.

You also need to have the probe assigned to a Tool # in the Tool Table, with its 'Type' set to 'Touch Probe', and have it activate/mounted via a Tool Call.

On machines that do not have spindle orientation or if you are using a corded probe or cordless UD probe and cannot orient the spindle 180 degrees during calibration, the spindle probe stylus needs to be indicated true to the spindle centerline.

Also, before calibrating the probe with a wired type probe, the center of spindle rotation must be indicated exactly over the probe gauge center. In this case the accuracy of the spindle probe is only as good as the stylus concentricity to the spindle and the closeness to the probe gauge center. Calibration must be done at least once before using the spindle probe. Once calibrated, calibration does not have to be done again unless you replace the probe stylus.
