- 305 -
B) If the components of the direction vector of the rotation
axis are in two directions (type B)
This is a case in which the rotation axis rotates about an
axis on the plane formed by any two of the basic three axes.
1) Set the axis number for the rotation axis and linear
axes 1, 2, and 3.
2) Linear axes 1, 2, and 3 are supposed to form a right-
handed system in that order.
3) The angle must satisfy the following:
- Rotation is on the plane of linear axes 3 and 1.
- The rotation of the angle in the plus direction is its
rotation from the plus direction of linear axis 3 to
the plus direction of linear axis 1.
- The angle assumed at the time of a match with the
direction of linear axis 3 is 0 degrees.
4) The rotation axis must satisfy the following when the
angle is 0 degrees:
- The rotation axis rotates about an axis orthogonal
to the plane of linear axes 1 and 2.
- The rotation of the rotation axis in the plus
direction is its rotation from the plus direction of
linear axis 1 to the plus direction of linear axis 2.

dimensional cutter compensation for rotary table, thermal growth
compensation along tool vector, and three-dimensional tool
compensation.
