<GeoAxElementName>:
Example
For the first transformation, the names of the elements of the kinematic chain currently in effect,
which define the geometry axes, are "X_AXIS", Y_AXIS" and "Z_AXIS", must be entered.
Program code
N100 $NT_GEO_AX_NAME[1,0] = "X_AXIS"
N110 $NT_GEO_AX_NAME[1,1] = "Y_AXIS"
N120 $NT_GEO_AX_NAME[1,2] = "Z_AXIS"

$NT_ROT_AX_NAME

Function
A maximum of three names ($NT_NAME (Page 279)) of the elements of the kinematic chain
that is currently in effect, which define the rotary axes of the transformation type (Page 256) to
be parameterized, must be entered in the system variable.
● Orientation transformation: The orientation axes A, B, C
● Face end (TRANSMIT) and cylinder surface transformation (TRACYL): The rotary axis,
which rotates the workpiece and, together with a linear axis, defines the polar coordinate
system.
Order of definitions
The maximum three rotary axes, beginning at Index 0, must be entered in the system variables
in the order in which they are defined in the kinematic chain that is currently in effect.
The kinematic chain must be run through as follows:
1. Starting point: Workpiece reference point
2. Elements of the chain
3. End point: Tool reference point
