General information
To measure tool and workpiece dimensions, a touch-trigger probe is required that provides a
signal change (edge) when deflected.
The probe must operate virtually bounce-free.
Different types of probe are offered by different manufacturers. Probes are distinguished
according to the number of measuring directions.
• Monodirectional (mono probe)
• Bidirectional
• Multidirectional (multi probe)
The probe type is defined by a parameter (_PRNUM) in measuring cycles (see Section
2.10).
Monodirectional probe
This type of probe can only be used if the spindle can be positioned with NC function SPOS
and the switching signal of the probe can be transmitted through 360° to the receiving station
(at the machine column).
The probe must be mechanically aligned in the spindle to permit measurements in the
following directions at the 0 degree position of the spindle.
