Functions in touch probe cycles
Soft keys that are used to select the probing direction or a probing
routine are displayed in the manual touch probe cycles. The soft
keys displayed vary depending on the respective cycle:
Soft key Function
Select the probing direction
Capture the actual position
Probe hole (inside circle) automatically
Probe stud (outside circle) automatically
Probe a model circle (center point of several
elements)
Select a paraxial probing direction for probing
of holes, studs and model circles
Automatic probing routine for holes, studs and model circles
If you use a function for probing a circle
automatically, the TNC automatically positions
the touch probe to the respective touch points.
Ensure that the positions can be approached without
collision.
If you use a probing routine for automatically probing a hole or a
stud, or a model circle, the control opens a form with the required
entry fields.

Function
Diameter of probe contact (optional for
holes)
Distance to the probe contact in the
plane
Positioning of touch probe in spindle
axis direction (starting from the
current position)
Angle for the first probing operation
(0° = positive direction of principal
axis, i.e. in X+ for spindle axis Z). All
other probe angles result from the
number of touch points.
Number of probing operations (3 to 8)
