Operation Mode
The TNC must be specially prepared by the machine tool
builder for the use of a 3-D touch probe.
After you press the NC START button, the touch probe approaches
the workpiece in a paraxial movement in the selected probe
function. The machine tool builder sets the probe feed rate (see
figure at right). When the probe contacts the workpiece, it
■ transmits a signal to the TNC: the coordinates of the probed
position are stored,
■ stops moving, and
■ returns to its starting position in rapid traverse.
If the stylus is not deflected within a defined distance, the TNC
displays an error message (MP 6130).
