12.2 The PLANE Function: Tilting the Working Plane (Software Option 1)
Defining the machining plane with Euler angles:
EULER PLANE
Function
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
The sequence of the rotations described above is
independent of the active tool axis.
Parameter description for the positioning behavior: See
“Specifying the positioning behavior of the PLANE
function” on page 400.
