2-1/2 External NPT on Okuma Lathe

[jdr1961]

Hi, group. Would someone be kind enough to post the code for a 2-1/2" NPT external thread for an Okuma L370 Captain lathe? I would appreciate the assistance.

G71X__ Z__ B__D__U__H__ F=1/pitch (I or A)

X : Final diameter of thread
Z : Z coordinate of end point of thread
A : Taper angle
I : Difference in radius between starting point and end point for taper thread
(expressed as a radius)
For taper thread, use either an A or I word.
B : Infeed angle
(0° x B < 180°; 0° if no designation. Normally it is equal to the cutter tip point angle.)
D : Depth of cut in the first thread cutting cycle
(Expressed as a diameter)
U : Finishing allowance
(Expressed as a diameter; no finishing cycle is performed if no U word is designated.)
H : Thread height
(Expressed as a diameter)
F : Thread lead
