13.1 General information about touch probe
cycles
HEIDENHAIN only gives warranty for the function of the
probing cycles if HEIDENHAIN touch probes are used.
The control must be specially prepared by the machine
tool builder for the use of a 3-D touch probe.
Touch-probe functions are not possible in combination
with the Global Program Settings function. If at least one
settings possibility is active, the control displays an error
message if a manual touch-probe function is selected or
when executing an automatic touch-probe cycle.

Method of function

Whenever the TNC runs a touch probe cycle, the 3-D touch probe
approaches the workpiece in one linear axis. This is also true during
an active basic rotation or with a tilted working plane. The machine
tool builder will determine the probing feed rate in a machine
parameter.

Cycles", page 495
When the probe stylus contacts the workpiece,
the 3-D touch probe transmits a signal to the TNC: the
coordinates of the probed position are stored,
the touch probe stops moving, and
returns to its starting position at rapid traverse.
If the stylus is not deflected within a defined distance, the TNC
displays an error message (distance: DIST from touch probe table).
