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:
See "Specifying the positioning behavior of the
PLANE function", page 371.
