8.2 Setting the parameters for workpiece measurement and
calibration
The necessary entries are input with operator guidance in the selection display, "WORKPIECE
MEASUREMENT". The following parameters must be set.
• Drilling axis
Permissible input values are 1 for X axis (machining plane YZ)
2 for Y axis (machining plane ZX)
3 for Z axis (machining plane XY).
• Number of probe
Depending on the number of workpiece probes defined in installation, any value between 1
and 14 can be entered.
• D number
Here you enter the D number under which the geometry data of the probe are stored.
• Measuring speed
Path increment a is usually 1mm but can be increased or decreased when calling
measuring cycles with parameter R28. If a > 1 is defined, the approach velocity is
automatically increased from 150mm/min to 300 mm/min. This value was selected to
ensure that the braking distance is less than the permissible deflection of the probe.
