- These parameters set the relationship between the rotation axis
and rotation plane.
- Two groups can be set. Therefore, machines controlled with two
rotation axes are supported.
- In the calculation of the tool direction, calculation for the
rotation axis of the first group is made first, then based on the
calculation result, calculation for the rotation axis for the second
group is made.
- When two rotation axes are used, the rotation plane may be
changed by the rotation of the other rotation axis. In this case, set
the rotation plane obtained when the rotation axis position is 0
degrees.
- When there is one rotation axis, set the rotation axis of the
second group to 0.
- In general, the direction vector of a rotation axis has three direction
components. This function supports direction vectors with one
direction component and two direction components. In each case,
set the following:
A) When the direction vecotor of a rotation axis has one
direction component (type A)
The rotation axis rotates about one of the basic three axes.
1) Set axis numbers for the rotation axis, linear axis 1,
and linear axis 2.
2) Set the linear axis 3 and the angle of inclination to 0.
3) The rotation axis is defined as follows:
- The rotation axis rotates about an axis that
perpendicularly intersects the plane formed by linear
axis 1 and linear axis 2.
- When the rotation axis rotates from the positive
direction of linear axis 1 to the positive direction of
linear axis 2, the rotation axis is said to rotate in the
positive direction.

B) When the direction vector of a rotation axis has two
direction components (type B)
The rotation axis rotates about an axis that lies in a plane
formed by any two of the basic three axes.
