Defining the working plane with the projection angle:
PLANE PROJECTED
Application
Projection angles define a working plane by specifying two angles
that you can communicate by projection of the 1st coordinate plane
(Z/X on tool axis Z) and 2nd coordinate plane (Y/Z on tool axis Z) to
the working levels to be defined.
Programming notes:
The projection angles correspond to the angle
projections on the planes of a rectangular coordinate
system. The angles at the outer faces of the
workpiece only are identical to the projection
angles if the workpiece is rectangular. Thus, with
workpieces that are not rectangular, the angle
specifications from the engineering drawing often
differ from the actual projection angles.
You can select the desired positioning behavior.
