6.8.2 PROBING (G75)
With function G75, it is possible to make movements ending when the CNC receives
the signal from a touch probe.
The definition format is:
G75 X Y
After G75, the desired axes must be programmed followed by the coordinates of the
target point.
The axes will move in G01 and at the programmed feedrate F until the external signal
from the touch probe is received. At that point, the CNC will conclude the block
assuming as theoretical position of the axes their real position at the time.
If the axes reach their target position before the CNC receives the probe signal, the
CNC stops the axes and issues error 21.
Attention:
G75 is not modal. Therefore, it must be programmed every time. It also
implies function G01 which means that after a G75 block, the CNC assumes
function G01.
The programmed feedrate cannot be overridden during the probing move.
Once G75 is executed, it is possible to assign the position of each axis to
any arithmetic parameter and, by using arithmetic programming, generate
special programs for measurement and calibration of tools and parts.
