Compatibility
The GETTCOR function is used in conjunction with the TOOLENV and SETTCOR functions to
replace parts of the functionality, which were previously implemented externally in the
measuring cycles.
Only some of the parameters, which actually determine the effective tool length, were
implemented in the measuring cycles. The above functions can be configured to reproduce
the behavior of the measuring cycles in relation to the tool length calculation.

Tool lengths L1, L2, L3 assignment: LENTOAX

2.11
LENTOAX function
The "LENTOAX" function provides information about the assignment of tool lengths L1, L2
and L3 of the active tool to the abscissa, ordinate and applicate. The assignment of
abscissa, ordinate and applicate to the geometry axes is affected by frames and the active
plane (G17 - G19).
Only the geometry component of a tool ($TC_DP3[x,y] to $TC_DP5[x,y]) is considered, i.e., a
different axis assignment for other components (e.g., wear) has no effect on the result.
The "LENTOAX" function is a predefined subprogram.
It must, therefore, be programmed in a separate block.

2.11 Tool lengths L1, L2, L3 assignment: LENTOAX
Calculates the tool length of the currently active tool in the machine
coordinate system allowing for all components.
Calculates the tool length for the active tool, consisting of the adapter
or tool base dimension, geometry and wear. Further components,
such as toolholder with orientation capability or kinematic
transformation, are not considered. The workpiece coordinate system
is used for the output.
Calculates the complete tool length of the active tool without allowing
for the length components of an active kinematic transformation.
Output in the basic coordinate system.
Calculates the complete tool length in the machine coordinate system
for the tool stored in the tool environment named "Testenv1". The
calculation is performed for cutting edge number D3, regardless of the
cutting edge number stored.
