First block of the G76 Threading cycle
G76 : G code for threading cycle.
P : P actually consists of multiple values which control the thread behavior,
- 01 : Number of spring passes or spring cuts.
- 00 : Thread run out at 45 degree
- 60 : Flank angle or Infeed angle
Q : Depth of normal cut ( these values are given in hundreds, so the depth of cut will be 0.1 ).
R : Depth of Last or Finish cut
Second block of the G76 Threading cycle
G76 : G code of the threading cycle.
X : The end value in x-axis.
Z : The end value in z-axis.
P : Thread depth ( as radius value ).
Q : Depth of first cut.
F : Thread Pitch
R : Thread Taper
