Probes that can be used

General information
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.
The probe must operate virtually bounce-free. Most sensors can be adjusted mechanically to
ensure that they operate in this manner.
Different types of probes supplied by a variety of manufacturers are available on the market.
Probes are therefore divided into three groups according to the number of directions in which
they can be deflected (see figure below).

Probe type
Multi-directional
Bi-directional
Mono-directional
While bi-directional probes are used on turning machines for workpiece measurements, a
mono-probe can also be used for this purpose on milling and machining centers.
Multidirectional probe (3D)
This probe type can be used unconditionally for measuring tool and workpiece dimensions.
