Defining the working plane with the projection
angle: 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.
Before programming, note the following
You can only use projection angles if the angle
definitions are given with respect to a rectangular
cuboid. Otherwise there will be deformations on the
workpiece.

Input parameters
Proj. angle in 1st coord. plane?: Projected angle
of the tilted machining plane in the 1st coordinate
plane of the fixed machine coordinate system (Z/X
for tool axis Z, see figure at top right). Input range:
from –89.9999° to +89.9999°. The 0° axis is the
principal axis of the active working plane (X for tool
axis Z. See figure at top right for positive direction)
Proj. angle in 2nd coord. plane? Projected angle
in the 2nd coordinate plane of the fixed machine
coordinate system (Y/Z for tool axis Z, see figure
at top right). Input range: from –89.9999° to
+89.9999°. The 0° axis is the minor axis of the
active machining plane (Y for tool axis Z)
ROT angle of tilted plane?: Rotation of the
tilted coordinate system around the tilted tool
axis (corresponds to a rotation with Cycle 10
ROTATION). The rotation angle is used to simply
specify the direction of the principal axis of the
working plane (X for tool axis Z, Z for tool axis Y;
see figure at bottom right). Input range: –360° to
+360°
