Automatic probing routine for holes, studs and model circles
NOTICE
Danger of collision!
The control does not perform an automatic collision check with
the stylus. During automatic probing procedures the control
positions the touch probe to the probing positions automatically.
There is a risk of collision if pre-positioning was not correct or if
obstacles have been ignored.
Program a suitable pre-position
Use safety clearances to take obstacles into account
If you use a probing routine for automatic probing of a hole, stud,
or a pattern circle, the control opens a form with the required entry
fields.
Input fields in the Measure stud and Measure hole forms
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°)
Automatic probing routine:
Pre-position touch probe
