7. When calibrating the length of the workpiece probe in Z0, enter the
reference point of the surface based on the active work offset (e.g. of
the workpiece or the machine table).
When calibrating the probe ball radius, enter a ∅ corresponding the
diameter of the calibration bore.
8. Press the <CYCLE START> key.
The calibration starts.
When the length is calibrated, the length of the workpiece probe is
calculated and entered in the tool list.
When calibrating the radius, the exact hole center point is determined
first. Then the four trigger points on the inside wall of the hole are
approached.
This procedure is carried out automatically twice: First with 180° (to the
starting position of the working spindle) and then in its starting position.
Note
User-specific defaults
"Setting ring diameter"
For the entry field "Diameter setting ring" (diameter, reference piece), fixed values can be
separately entered at parameters for each probe number (calibration data set number). If
these parameters are assigned, the values saved there are displayed in the entry field
"Diameter setting ring"; however, they can no longer be changed there.
"Height of the reference surface in the infeed axis"
For the entry field "Height of the reference surface" fixed values can be separately
entered at parameters for each probe number (calibration data set number). If these
parameters are assigned, the values saved there are displayed in the entry field "Height
of the reference surface"; however, they can no longer be changed there.
Please refer to the machine manufacturer's specifications.
