          X: Coordinates of ending point for thread cutting end face

          Z: Final cut depth for thread cutting

          A: Taper angle

          I: Difference between start and end points for taper thread cutting (Instruct A or I only for taper thread.)

          B: Cut angle  (The range is 0<=B<180.  If not instructed, it is regarded as 0, the same as the cutter angle of  ordinary tool.)

          E: Pitch change distance per pitch for variable pitch thread

          F: Thread pitch instruction  (When J is instructed, F/J pitch  is used.)

          J: Number of threads within the distance instructed by F (If not instructed, J=1.)

          M: This M code instructs the cut mode and cut pattern for  the thread cutting.

          M32: Single blade cut mode
