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
