Input parameters
U Proj. angle 1st coordinate 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).
U Proj. angle 2nd coordinate 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).
U ROT angle of the 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°
U Continue with the positioning properties (see
"Specifying the positioning behavior of the PLANE
function" on page 366)
