Parameters
T Tool of type 3D probe
X Approach position in X direction (abs.)
Y Approach position in Y direction (abs.)
Z Approach position in Z direction (abs.)
Zero off. Work offset where the workpiece zero is to be saved.

•
Approach +: The probe approaches the workpiece in the plus direction
direction –: The probe approaches the workpiece in the minus direction
At the approach position in the Z direction, this parameter does not apply as the tool
can only approach the workpiece in a negative direction!
X0, Y0, Z0 Setpoint position of the workpiece edge

During automatic measurement, the measuring probe first moves at
rapid traverse and then at measuring infeed to the edge of the
workpiece and back. The measuring infeed is defined in a machine
data.
Please refer to the machine manufacturer's instructions.
The workpiece radius is considered during calculation of the
workpiece zero and is stored in a work offset.
Insert an electronic measuring probe in the spindle (see Sec.
"Programming the tool, offset value, and spindle speed").
Select the "Misc." and "Workpiece zero" softkeys.
>
Use the softkeys to select in which axis direction you want to
approach the workpiece first.
Enter the values for the individual parameters.
Press the "Accept" softkey.
Repeat the process for the other two axes.
Basic work offset
Work offset (the values are saved in the coarse offset and existing values in the
fine offset are deleted.)
GUD data (you to scan the measurement result in GUD E_MEAS, e.g. for other
calculations (tolerance checks, etc.)).
