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
 Swivel angle of tool axis?: Tilting angle EULNU 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 494)
