-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.
1) Set axis numbers for the rotation axis, linear axis 1, linear axis 2, and
linear axis 3.
2) The linear axes 1, 2, and 3 form a right-handed coordinate system in
this order.
3) The angle of inclination is defined as follows:
-Rotation is performed in the plane formed by linear axes 3 and 1.
-When the rotation axis rotates from the positive direction of linear
axis 3 to the positive direction of linear axis 1, the angle of
inclination is positive.
-When the rotation axis and linear axis 3 match, the angle of
inclination is 0 degrees.
4) When the angle of inclination is 0 degrees, the rotation axis is defined
as follows:
-The rotation axis rotates about an axis that perpendicularly intersects
the plane formed by linear axes 1 and 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.
