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.

Changing tool components

SETTCOR function
The SETTCOR function is used to change tool components taking into account all general
conditions that can be involved when evaluating the individual components.
The SETTCOR function is a predefined subprogram. It must, therefore, be programmed in a
separate block.
Note
Regarding the terminology: If in the following, in conjunction with the tool length, tool
components are involved, then the components considered from a vectorial perspective are
meant, which make up the complete tool length, e.g. geometry or wear. Such a component
comprises three individual values (L1, L2, L3), which are called coordinate values in the
following.
The tool component "geometry" therefore comprises three coordinate values $TC_DP3 to
$TC_DP5.
Syntax:
Status = SETTCOR(_CORVAL, _COMP, _CORCOMP, _CORMODE, _GEOAX, _STAT,
_T, _D, _DL)
With the exception of the first two parameters (_CORVAL and _COMP) all of the param‐
eters can also be omitted.
Value/parameter:
Status
1526
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 cal‐
culation is performed for cutting edge number D3, regardless of the
cutting edge number stored.
