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:
Automatic probing routine for holes and studs
If you use a probing routine for probing a hole or a stud automatically,
the TNC opens a form with the required input fields.
Input fields in the Measure a stud and Measure hole forms:
Soft key Function
Select the probing direction
Capture the actual position
Probe hole (inside circle) automatically
Probe stud (outside circle) automatically
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.
Input field Function
Stud diameter? or
Hole diameter?
Diameter of probe contact (optional for
holes)
Safety clearance? Distance to the probe contact in the
plane
Incr. clearance
height? Positioning of touch probe in spindle axis
direction (starting from the current
position)
Starting angle? 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 touch
points? Number of probing operations (3 to 8)
Angular length? Probing a full circle (360°) or a circle
segment (angular length < 360°)
