3.3.20 3D - sphere (CYCLE997)
Function
This measuring variant can be used to measure a sphere. Measuring can be parallel to the
axis or on a circular path in the workpiece coordinate system.
The center point (position of the sphere) for a known diameter is determined from three or four
measuring points at the circumference and one measuring point at the "north pole" of the
sphere. With the selection "Determine sphere diameter" and "No repeat measurement", using
an additional measurement, the sphere diameter is correctly determined.
If "Determine sphere diameter" and "With repeat measurement" are selected, the additional
measurement is performed in the 1st pass only.
In the 2nd pass (repeat pass), the diameter is calculated internally without an additional
measurement.
Measuring cycle CYCLE997 can measure the sphere and, in addition, automatically correct a
work offset (WO) in the translational offsets of the three axes of the active plane on the basis
of the position of the sphere center.
