Input parameters
8 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 machining plane (X for tool axis Z.
See figure at top right for positive direction).
8 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).
8 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 machining plane
(X for tool axis Z, Z for tool axis Y; see figure at bottom
right). Input range: from 0° to +360°.
8 Continue with the positioning properties (see
“Specifying the Positioning Behavior of the PLANE
Function” on page 482).
