thread cutting. For thread interpolation, the feed axis rotates along with the
spindle, the long axis moves one pitch when the spindle rotates one rev,
and the short axis and the long axis directly interpolate.
Example:

1.3.5 Absolute Programming & Incremental Programming
Specify coordinate values of path’s end point or target position in programming and there are 3
kinds of programming method according to coordinate values in programming: absolute programming,
incremental programming and compound programming.
Programming with X/Z axis absolute coordinate value to program (present with X, Z) is defined to
be the absolute programming;
Programming with X/Z axis incremental movement (present with U, W) is defined to be the
incremental programming;
In the system, X, Z axis separately uses the absolute programming and incremental program,
which is called the compound programming.
Example: A → B linear interpolation
