Input parameters

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.

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.

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.

Continue with the positioning properties (see

“Specifying the positioning behavior of the PLANE
function” on page 560).
