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.
îš¾ Insert an electronic measuring probe in the spindle (see Sec.
"Programming the tool, offset value, and spindle speed").

Zero off. Work offset where the workpiece zero is to be saved.
• 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.)).
pproach
direction
+: The probe approaches the workpiece in the plus direction
–: The probe approaches the workpiece in the minus direction
t the approach position in the Z direction, this parameter does not apply as the tool
can only approach the workpiece in a negative direction!
