Defining the working plane with the Euler angle:
PLANE EULER

Application

Euler angles define a machining plane through up to three

rotations about the respectively tilted coordinate system

. The

Swiss mathematician Leonhard Euler defined these angles. When
applied to the machine coordinate system, they have the following
meanings:

Precession angle:
EULPR

Rotation of the coordinate system
around the Z axis

Nutation angle:
EULNU

Rotation of the coordinate system
around the X axis already shifted by the
precession angle

Rotation angle:
EULROT

Rotation of the tilted machining plane
around the tilted Z axis

Before programming, note the following

Parameter description for the positioning behavior:

PLANE function", page 365
