I was wondering if someone could give me some info on how to thread an internal thread on my Hardinge T42 with Funuc 18t
Heres how I would thread an O.D.thread

(THREADING 25mm X 1.5p O.D.Thread)
N1
G97 S650 M13
T101
G0 X1.0506 Z.25
S650
G4 U.6
G76 P030029 Q0025 R.0
G76 X.9054 Z-.500 P0363 Q0040 F.059055
G0 X1.250
Z6.0
M01

What would I change to do the same thread internally?
Thanks
Brian
