ROT
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
Swiss mathematician Leonhard Euler defined these angles. When
applied to the machine coordinate system, they have the following
meanings:
Precession angle:
EULPR
Nutation angle:
EULNU
Rotation angle:
EULROT
Before programming, note the following
Parameter description for the positioning behavior.
