G92- Threading cycle. Straight infeed only.
G92 X.22 Z.3 F.05 (R-.002) FOR 1/4-20
G0 X.5 Z-.05 (ENDS G92 CYCLE. IF NO G0 THEN ALARM!)
X.1876 = Each cutting pass
Z.3 or (W) =The ending Z of the thread
F.05 =Feed-rate 20 TPI 1/20=.05
R = R is optional for tapered threading. R is the amount of
difference in X from start to finish in Z. When cutting threads
moving Z and X in a positive direction R is a negative value.
