Multi probe
A multi(directional) probe is one that can deflect in three dimensions.
Multiple measurement at the same location
Parameter _NMSP can be used to determine the number of measurements at the same
location. The actual/set difference is determined arithmetically.
Offset angle position
If a -> mono probe is used, the position of the probe can also be corrected for machine-
specific reasons using the parameter _CORA.
Offset axis
With some measuring variants, for example, in CYCLE998, positioning in another axis that
must be defined, also called offset axis can be performed between measurements in the
measuring axis. This must be defined in parameter _MA with offset axis/measuring axis.
on-the-fly measurement
This method processes the probe signal directly in the NC.
Paraxial measurement
A measuring variant used for paraxial measurement of a workpieces, such as a drill-hole,
shaft, rectangle, etc. The measuring path is traveled paraxially.
Positional deviation
The positional deviation (skew) describes the difference between the spindle center and the
probe tip center ascertained by calibration. It is compensated for by the measuring cycles.
Probe ball diameter
The active diameter of the probe ball. It is ascertained during calibration and stored in the
measuring cycle data.
Probe type
In order to measure tool and workpiece dimensions, a touch-trigger probe is required that
supplies a constant signal (rather than a pulse) when deflected.
Probes are therefore classified in three groups according to the number of directions in
which they can be deflected.
• Multidirectional
• Bidirectional
• Monodirectional (mono probe)
