Glossary
Mono probe
A mono(directional) probe is a probe that can only deflect in one direction. It can only be used
for workpiece measurement on milling machines and machining centers with slight limitations.
Multi probe
A multi(directional) probe is one that can deflect in three dimensions.
Multiple measurement at the same location
Parameter S_NMSP can be used to determine the number of measurements at the same point.
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 variants, 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 S_MA with offset axis/
measuring axis.
Paraxial measurement
A measuring variant used for paraxial measurement of a workpiece, such as a hole, spigot
(shaft), rectangle, etc. The measuring path is traversed paraxially in the WCS.
Part chain
The part chain is a part chain of the kinematic chain and runs parallel to the tool chain. The
part chain begins in the root element and ends at the workpiece clamping.
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.
