Input parameters
8 Rot. angle main coordinate plane?: Rotary angle
EULPR around the Z axis (see figure at top right). Note:
„ Input range: –180.0000° to 180.0000°
„ The 0° axis is the X axis.
8 Tilting angle tool axis?: Tilting angle EULNUT of the
coordinate system around the X axis shifted by the
precession angle (see figure at center right). Note:
„ Input range: from 0° to 180.0000°
„ The 0° axis is the Z axis.
8 ROT angle of the tilted plane? : Rotation EULROT of
the tilted coordinate system around the tilted Z axis
(corresponds to a rotation with Cycle 10 ROTATION).
Use the rotation angle to simply define the direction
of the X axis in the tilted machining plane (see figure
at bottom right). Note:
„ Input range: from 0° to 360.0000°
„
The 0° axis is the X axis.
8 Continue with the positioning properties (see
“Specifying the Positioning Behavior of the PLANE
Function” on page 482).
