Cycles
TNC 407/TNC 415 B/TNC 425
Start of activation
Cycle 19 becomes effective as soon as it is defined in the part program.
If the function TILTING PROGRAM RUN is activated in MANUAL mode
(see page 2-11), the angle value entered in this menu will be overwritten
by cycle 19.
Input data
ROTARY AXIS AND ANGLE:
Rotated axis with tilt angle.
Axes A, B and C are programmed with soft keys.
Entry of an angular axis and the associated angle in cycle 19 does not result in movement of the axis. You must
move the axis to the corresponding angle, for example with an L block.
Cancellation
Define the cycle again, entering NO ENT for all data.
Position angular axis
To machine in a tilted plane, the corresponding angular axis is positioned
to the required angle conventionally—normally with an L block.

Position display in a tilted system
Upon activation of cycle 19 the displayed positions (ACTL. and NOML.)
and the datum are referenced to the tilted coordinate system. The posi-
tions displayed immediately after cycle definition may not be the same as
the coordinates of the last programmed position before cycle 19.
As soon as you move an axis in a tilted system, the compensation for this
specific axis is activated. You must move all axes to activate compensa-
tion for all axes.
Work space monitoring
In the tilted coordinate system, the TNC checks for limit switches only in
the axes which are moved. An error message will be output if necessary.
