ú Program name: Enter the name of the program you
want to call and, if necessary, the directory it is located
in.
The program is called with
■ G79 (separate block) or
■ M99 (blockwise) or
■ M89 (modally)
Example: Program call
A callable program 50 is to be called into a program via a cycle call.

ORIENTED SPINDLE STOP (Cycle G36)
The TNC and the machine tool must be specially
prepared by the machine tool builder for the use of Cycle
G36.
The control 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
Effect
The angle of orientation defined in the cycle is positioned to by
entering M19.
If you program M19 without having defined Cycle G36, the TNC
positions the machine tool spindle to an angle that has been set in
a machine parameter (see your machine manual).
ú Angle of orientation: Enter the angle according to the
reference axis of the working plane.
Input range 0 to 360°
Input resolution 0.001°
