1.6 Probes that can be used
General information
To measure tool and workpiece dimensions, an electronic touch-trigger probe is required
that provides a signal change (edge) when deflected with the required repeat accuracy.
The probe must operate virtually bounce-free.
Different types of probe are offered by different manufacturers.
Note
Please observe the information provided by the manufacturers of electronic probes and/or
the machine manufacturer's instructions on the following points:
 Electrical connection
 Mechanical calibration of the probe
 If a workpiece probe is used, both the direction of deflection and transmission of
Probes are distinguished according to the number of measuring directions.
● Multi-directional (multi probe)
● Mono directional (mono probe)

Multi-directional (3D)
The probes also differ in the form of the stylus tip:
the measuring cycles support pin, L and star probes as autonomous tool types. The use of
the probe types is referenced in the individual measuring cycles. The multi probe is
universally applicable.
The use of probes requires a spindle that can be positioned. For a mono probe, the
switching direction is tracked for each measurement by turning the spindle. This can lead to
a longer program runtime.

switching signal to the machine column (radio, infrared light or cable) must be taken into
account. In some versions, transmission is only possible in particular spindle positions or
in particular ranges. This can restrict the use of the probe.
