G31 Fixed thread cutting cycle: Longitudinal

        

[Command format]

          G31 X___ Z___ I__ (E__) F__ (K__) (L__) (J__) (C__)

                        A__

          X: Thread diameter at each thread cutting

          Z: Coordinates of thread cutting longitudinal end point

          F: Thread cutting pitch instruction                   (F/J pitch when J is instructed)

          I: Difference of radii between start and end points for taper  thread cutting

          A: Taper angle  (Instruct I or A only.)

          E: Pitch change per pitch for variable pitch thread cutting

          K: Z-axis shift distance for thread cutting start point (K=0 if not instructed)

          L: Thread overcutting distance (If not instructed, L is equal to one pitch at start of thread cutting.)   This is valid when thread cutting chamfering M code (M23) is instructed.

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

          C: Phase difference of thread cutting (If not instructed, C=0.)
