Spigot - rectangular spigot (CYCLE977)

Function
This measuring version can be used to measure a rectangular spigot on a workpiece. The
spigot width and spigot length are measured as well as the spigot center point determined.
Measurements are also possible at a rectangular spigot (horizontal) rotated in the working
plane. To do this, an angle corresponding to the real spigot position must be entered into the
parameterizing screen form. The probing at the sides of the spigot is always at right angles.
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 workpiece zero point is in relation to the center point of the
● 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
measurements start in the positive direction of the 1st geometry axis. The spigot width and
the spigot length are calculated from the 4 measured actual positions of the spigot sides,
taking into account the calibration values. Corresponding to the work offset selected to be
corrected, the position of the spigot center is determined as the workpiece zero. The
measuring differences of the side lengths are used as the basic quantity for a tool offset the
position of the spigot zero point as basis for the work offset.
