Edge distance - rib (CYCLE977)

Function
This measuring variant can be used to measure a rib on a workpiece. The rib width is measured
and the rib center point is determined.
Measurements at an inclined rib are also possible. To do this, an angle corresponding to the
actual angularity of the rib position should be entered into the parameterizing screen form.
Probing at the rib edge always takes place at right angles. A protection zone can be defined
at the side of the rib.
With the "3D probe with spindle reversal" measuring method, measurement is performed in
the axes of the plane as differential measurement. Two complete measurements of the rib are
automatically carried out one after the other, one with a spindle position of 180 degrees, and
one with 0 degrees. The special procedure for this measurement permits the use of an
uncalibrated multi-directional probe. However, the correct tool radius of the probe must be
determined once by calibrating the probe. Probe types 712, 713 and 714 are not suitable for
this purpose. A positionable spindle is mandatory.
With the "Align 3D probe" measuring method, the switching direction of the probe is always
aligned to the current measuring direction. This function is recommended when high demands
