If n is the content of the 100s digit of the setting data, the coordinate system is
rotated around the orientation vector by the angle n * 90 degrees. n may have the
values 0 to 3. Larger values are evaluated as if they were 0.
If the sign of the setting data is negative, the coordinate system is rotated around
the axis by 180 degrees, which is defined by the original position of the normal
orientation vector (that is, before any rotation due to n being unequal to 0).
Example:
If the content of the setting data is -18, then:
Orientation vector (0, -1, 0)
Normal orientation vector (1, 0, 0)
Binormal vector (0 , 0, -1)
Handling of tools with an explicitly programmed tool orientation by means of cutting
edge data ($TC_DPV..):
This setting data is normally ignored for tools for which the orientation is defined
in this way. This means that the programmed orientation vectors are assigned to the
geometry axes in response to the active machining plane (G17 - G19).
If the setting data is also active for such tools, the 1000s digit must be equal to 1.
However, the 100s digit and the sign are not evaluated. This means that the setting
data only defines how the orientation components are assigned to the geometry axis
directions. No additional rotations are performed.

Description: If this setting data is not equal to zero, the assignment of the tool orientation
components
of
turning
and grinding tools (tool types 400 to 599) to the geometry axes
is not changed if the machining plane changes (G17 - G19. It has no relevance for tools
other than turning and grinding tools.
The orientation coordinate system is determined by the orientation vector and a normal
orientation vector lying
at right-angles to it. It is completed by a third vector, the
binormal vector, which is given by the cross product of the normal orientation vector
and the orientation vector.
The basic orientation is determined by the units and tens digits of the setting data.
Apart from the
value 0, only the values 17, 18 and 19 are permissible. All other values
are treated as if their value were 18.

* Each value not equal to 0, which is not one of the listed values is evaluated as if
it were the value 18.
If n is the content of the 100s digit of the setting data, the coordinate system is
rotated around the orientation vector by the angle n * 90 degrees. n may have the
values 0 to 3. Larger values are evaluated as if they were 0.
