Measuring variants
2.3 Measure workpiece (milling)
2.3.17 3D - align plane (CYCLE998)
Function
This measuring variant can be used to determine and correct the angular position of a three-
dimensional oblique plane on a workpiece by measuring 3 points. The angles are in relation
to the rotation around the axes of the active plane G17 to G19.
The same requirements as for the simple angle measurement apply, see measuring version
Align edge (Page 100).
Additional data are required for the setpoint input of the 2nd angle. A correction is made in
the work offset in the rotary components (rotation) of the specified work offset (WO).
The translatory components of the WO remain unchanged, and should be corrected in a
subsequent measurement (e.g. set edge, corner).
After the measurement, at suitable machines where orientation transformation (swiveling,
TRAORI) is set up, the probe can be aligned perpendicular on the measuring plane
(machining plane).
● Swiveling: See the Programming Manual
● TRAORI
Measuring principle
The "Align plane" measuring variant is performed according to the 2-angle measurement
principle:
The angular offsets are in the rotary part of the geometry axes for a workpiece with a three-
dimensional oblique plane.
