Swiveling Yes: compute and swivel (swivel coordinate system and move swivel axes)
No: only compute, don't swivel (only swivel coordinate system, don't move swivel
axes)
Transformation Swiveling additive or new
X0 Reference point for rotation mm
Y0 Reference point for rotation mm
Z0 Reference point for rotation mm
Swivel method
xial swiveling, or swiveling via solid or projection angle
X
xis angle (axial swivel) The sequence of the axes Degr.
Y
xis angle (axial swivel) can be altered as required Degr.
Z
xis angle (axial swivel) with "Alternat." Degr.
α
ngle of rotation in the XY plane about the Z axis (swiveling via solid angle) Degr.
β
ngle of rotation in space about the Y axis (swiveling via solid angle) Degr.
Xα
xis angle (swiveling via projection angle) The sequence of the axes Degr.
Yα
xis angle (swiveling via projection angle) can be altered as required Degr.
Zβ
xis angle (swiveling via projection angle) with "Alternat." Degr.
X1 New zero point of rotated surface mm
Y1 New zero point of rotated surface mm
Z1 New zero point of rotated surface mm
Direction Preferred direction of rotation with 2 alternatives
+: Larger angle of the axis on the scale of the swivel head / swivel table
-: Smaller angle of the axis on the scale of the swivel head / swivel table
Fix tool tip Follow-up: The position of the tool tip is maintained during swiveling.
Do not correct: The position of the tool tip is changes during swiveling.
Other additive transformations can be added to the offsets before (X0,
Y0, Z0) or after (X1, Y1, Z1) swiveling (see Sec. "Work offsets").
Programming example
You want to bevel a corner on a cube. The oblique surface is
defined as the machining plane as follows:
• With axial swiveling and swiveling using solid angles, the system
of coordinates is rotated first in the XY plane in such a way that
the upper edge of the inclined surface of the cube runs parallel to
the X axis (rotate 45° about Z axis or α=45°). The system of
coordinates is then tilted so that the inclined plane of the cube is
in the XY plane (rotate -54.736° about Y axis -54.736° or
β=54.736°).
• With the swiveling via projection angles options, the X and Y
axes are rotated through 45° so that the inclined plane of the
cube is in the XY plane. The Z axis is then rotated through 30° so
that the X axis runs through the center point of the inclined
surface (zero point of rotated surface).
