Glossary
Multi probe
A multi(directional) probe is one that can deflect in three dimensions.
Multiple measurement at the same location
Parameter
The actual/set difference is determined arithmetically.
Offset angle position
When using a → mono probe, for machine-specific reasons it may be necessary to correct
the position of the probe using the tool data in mono probe type 712.
Offset axis
With some measuring versions, for example, measuring an angle 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
axis/measuring axis.
Paraxial measurement
A measuring version used for paraxial measurement of a workpiece, such as a hole, spigot
(shaft), rectangle, etc. The measuring path is traversed paraxially in the workpiece
coordinate system.
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
To measure tool and workpiece dimensions, an electronic touch-trigger probe is required
that provides a signal change (edge) when deflected.
Probes are distinguished according to the number of measuring directions.
● Multi-directional (3D, multi probe)
● Mono directional (mono probe)

can be used to determine the number of measurements at the same point.
