The following help displays relate to machining plane G17 (tool axis Z).
X0, Y0, Z0 (reference points prior to rotation)
Reference points
_MODE (swivel mode)
This parameter defines the swivel mode for the axis.
• Axial
• Projection angle
1)
• Solid angle
Swivel mode always refers to the coordinate system of
the workpiece and is therefore not dependent on the
machine.
You can set which swivel modes are available in
the CYCLE800 start-up menu.
• With the axial swiveling variant, the tool is rotated
about the individual axes in succession, with each
rotation starting from the previous rotation. The axis
sequence can be selected freely.
• When swiveling using the angle of projection, the
angle value of the swiveled surface is projected
onto the 1st two axes of the coordinate system. The
3rd rotation starts from the previous rotation. The
axis sequence can be selected freely.
• With the solid angle variant, the tool is rotated first
about the Z axis and then the Z axis. The second
rotation starts from the first.
The positive direction of each rotation for the
different swivel variants is shown in the help
displays.
1) Only available if machine manufacturer is
selected in the start-up screen form.
