Defining the working plane with projection angles:
PLANE PROJECTED
Application
Projection angles define a machining plane through the entry of two
angles that you determine by projecting the first coordinate plane (Z/
X plane with tool axis Z) and the second coordinate plane (Y/Z with
tool axis Z) onto the machining plane 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.
