18.12 Working with tool environments
Basic Functions
1584 Function Manual, 09/2011, 6FC5397-0BP40-2BA0
The following machine data no longer corresponds to the sum of l
1
and l
3
, but only to vector l
1
.
MD24560/24660 $MC_TRAFO5_JOINT_OFFSET_1/2 (vector of kinematic offset of the first 5-axis transf. in the
channel).
The new response is identical to the current response, if the following machine data equals zero:
MD24558/24658 $MC_TRAFO5_JOINT_OFFSET_PART_1/2 (vector kinematic offset in table).
GETTCOR examples
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.
GETTCOR(_LEN): Calculates the tool length of the currently active tool in the machine
coordinate system allowing for all components.
GETTCOR(_LEN; "CGW :
W" ):
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.
GETTCOR(_LEN, "-K :B" ): 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.
GETTCOR(_LEN, ":M",
"Testenv1",,3):
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.
