Cabling: The signal is transmitted through the cable. Its most important disadvantage is
its rigidness in moment. It is used in lathes and machining centers for final adjustments
of tools where the probe has a fixed measuring position and the tools are brought close to
the probes. It is also used in digitizing systems.
Inductive: It allows greater ease of movement. The signal is transmitted without physical
contact, by means of two opposing plates, across the work area.
Optical: Communication is made by means of infrared rays. One of its advantages is the
freedom to position the signal receiver outside the work area. Its applications are the same
as those of the inductive probe.
6.26.3. Most common applications
There are different applications, as shown below:
Fine adjustment of the tool: These check the cutting point of each tool and compensate,
if necessary, the distance to the work place or stop production should a tool break.
Fine adjustment of the part: by means of canned probe cycles which will be seen below.
Digitizing system. For copying parts by means of the collection of information point by
point. The probe is given the job of sending positional data by means of a series of
predetermined movements along the surface of the part.
In the case of the FAGOR 8025/30 TS CNC the system generates CNC programs
automatically enabling the machining of complex parts with a great deal of reliability.
It is recommendable to use an interface which is an electronic link between the probe and
the control of the machine.
This controls the status of the probe continuously, provides energy to the induction
modules and transmits a signal to the control of the machine when the probe has tripped.
