Touch trigger probe, probing feed rate: F in touch
probe table
In
F you define the feed rate at which the TNC is to probe the
workpiece.
Touch trigger probe, rapid traverse for positioning:
FMAX
In
FMAX you define the feed rate at which the TNC pre-positions
the touch probe, or positions it between measuring points.
Touch trigger probe, rapid traverse for positioning:
F_PREPOS in touch probe table
In
F_PREPOS you define whether the TNC is to position the touch
probe at the feed rate defined in FMAX or at rapid traverse.
Input value =
FMAX_PROBE: Position at feed rate from FMAX
Input value =
FMAX_MACHINE: Pre-position at rapid traverse
Multiple measurements
To increase measuring certainty, the TNC can run each probing
process up to three times in sequence. Define the number
of measurements in machine parameter
ProbeSettings >
Configuration of probe behavior > Automatic mode: Multiple
measurements with probe function. If the measured position
values differ too greatly, the TNC outputs an error message
(the limit value is defined in
Confidence interval of multiple
measurements). With multiple measurement it is possible to
detect random errors, e.g. from contamination.
If the measured values lie within the confidence interval, the TNC
saves the mean value of the measured positions.
Confidence interval of multiple measurements
When you perform a multiple measurement, you store the
value that the measured values may vary in
ProbeSettings >
Configuration of probe behavior > Automatic mode: Confidence
interval of multiple measurements. If the difference in the
measured values exceeds the value defined by you, the TNC
outputs an error message.
