Spigot - 1 circular spigot (CYCLE977)

Function
This measuring version can be used to measure a circular spigot on a workpiece.
The spigot diameter is measured and the spigot center point is determined. The
measurements are always performed parallel to the geometry axis of the active plane.
With a starting angle, the measuring points can be shifted along the circumference of the
spigot. A protective zone can be defined around the spigot.
The measurement result (measurement difference) can be used as follows:
● Correction of a WO so that the zero point is in relation to the center point of the spigot.
● Offset of a tool,
● Measurement without offset
Measuring principle
2 opposite points in each of the two geometry axes of the plane are measured. The spigot
diameter and the center point are calculated from these 4 measured actual positions, taking
into account the calibration values. From the measuring points of the 1st geometry axis of
the plane, the center of this axis is calculated and the probe positioned at this center.
Starting from this center point, the two points in the 2nd geometry axis are measured, from
which the actual spigot diameter is determined. The measurements start in the positive
direction of the 1st geometry axis. The measured difference of the spigot diameter is used as
tool offset and the position of the spigot zero point as basis for a work offset.
