12.4 SPINDLE ORIENTATION (Cycle 13, DIN/
ISO: G36)
Cycle function
Machine and TNC must be specially prepared by the
machine tool builder for use of this cycle.
The TNC can control the machine tool spindle and rotate it to a given
angular position.
Oriented spindle stops are required for
Tool changing systems with a defined tool change position
Orientation of the transmitter/receiver window of HEIDENHAIN 3-
D touch probes with infrared transmission
The angle of orientation defined in the cycle is positioned to by
entering M19 or M20 (depending on the machine).
If you program M19 or M20 without having defined Cycle 13, the
TNC positions the machine tool spindle to an angle that has been set
by the machine manufacturer (see your machine manual).

Please note while programming:
Cycle 13 is used internally for Cycles 202, 204 and
209. Please note that, if required, you must program
Cycle 13 again in your NC program after one of the
machining cycles mentioned above.
