458 Programming: Multiple Axis Machining
12.2 The PLANE Function: Tilting the Working Plane (Software Option 1)
Input parameters
U Rot. angle main coordinate plane?: Rotary angle
EULPR around the Z axis (see figure at top right).
Please note:
Input range: –180.0000° to +180.0000°
The 0° axis is the X axis
U 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). Please
note:
Input range: 0° to +180.0000°
The 0° axis is the Z axis
U 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). Please note:
Input range: 0° to 360.0000°
The 0° axis is the X axis

“Specifying the positioning behavior of the PLANE
function” on page 466)
