5.1 General information on touch probe
cycles (software option)
Fundamentals
Refer to your machine manual.
The control must be specially prepared by the machine
tool builder for the use of a 3-D touch probe.
HEIDENHAIN gives a warranty for the function of the
touch probe cycles only if HEIDENHAIN touch probes are
used!
Principle of function of touch probe cycles
When you run a touch probe cycle, the 3-D touch probe is pre-
positioned at positioning feed rate. The actual probing movement
is then executed from there at probing feed rate. The machine tool
builder determines the positioning feed rate for the touch probe in a
machine parameter. You define the probing feed rate in the respective
touch probe cycle.
When the probe stylus contacts the workpiece,
the 3-D touch probe transmits a signal to the control: the
coordinates of the probed position are stored,
the touch probe stops moving, and
returns to the starting position of the probing procedure at
positioning feed rate.
If the stylus is not deflected within a defined distance, the control
displays an error message.
