Fanuc 31i Control Nakamura Tome Mul;ti tasking Mill Turn


Recommended Posts

Hello Forum

 

We have (3) NTY 3 and (1) NT250 Nakamura Tome MillTurns all with Fanuc 31i controls, in the G71 cycle 2 machines allow as the book shows the Last N# called out by the Q in the Canned Parameters line of the cycle to have data in it

 

(SOLIDTURN - ROUGHING)
G00X3.5Z.05
G71U.1R.02
G71P1000Q1001U.01W.003F.01
N1000G00X2.3095
G01Z-.55F.01
X3.3338
G03X3.385Z-.5756I0.K-.0256
G01Z-1.013
N1001X3.5

 

and 2 machines will alarm out unless the Last N# called out by Q in the canned cycle is alone

This to me seems like a parameter setting, would any of you know and be willing to share what parameter this might be?

Tyron and Millman thanks for your responses, Tyron I agree and the cycle automatically returns to the initial X, not here but that may be a machinist preference, however the N placement and the error are not. Millman I have sent this to support I am waiting for the response,expect it anytime now I will post the answer when it is figured out. We have one the Super NT250 with the touch screen, Mixed reviews from the machinists and I personally have not gotten used to touch screen and I really do not like touching screens because finger prints drive me nuts on my PC...
