Using Touch Probe Cycles

12.1 General information about touch probe cycles

12.1 General information about touch
probe cycles
HEIDENHAIN only warrants the function of the touch
probe cycles if HEIDENHAIN touch probes are used.
The TNC must be specially prepared by the machine
tool builder for the use of a 3-D touch probe.
Refer to your machine manual.

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.
Further Information:
Cycles, page 301
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).
Consideration of a basic rotation in the Manual
Operation mode
During probing the TNC considers an active basic rotation and
approaches the workpiece at an angle.
Touch probe cycles in the Manual Operation and
Electronic Handwheel operating modes
In the Manual Operation and El. Handwheel modes, the TNC
provides touch probe cycles that allow you to:
Calibrate the touch probe
Compensating workpiece misalignment
Setting datums
