Hi everyone, we are setting up a new(to us) lathe, fanuc 0i tc control and are trying to program a g74 cycle, program runs but what is happening is when it rapid retracts the set amount it feeds in from that point then continues feeding the set amount before rapid retract and feeding back in, my question is how can I change this to rapid retract then rapid back to where it left off, similar to a g83 on our milling machines?

bump.

On my 0i-td G74 is peck drilling. If I want to come out of the hole completely I use G83.

G83 X0 Z-1. R.1 Q0800 F.005

R is the return plane. Q is distance of infeed between withdrawals.

I believe your G74 cycle is doing exactly as it's supposed to.

Give that a whorl and and see what happens?

I also might add that on my control I've not had complete functionality of some of the canned cycles. Don't know exactly why? It May be that complete functionality is an extra paid option idk?

thank you very much for the help, the previous operator said the g83 cycle returned errors, could have been the "Q" value with a decimal that gave the problems, tried your code and worked no problem!!

No problem Dan...

Glad you have this matter sorted.

Yeah I'm pretty sure it was the Q decimal causing the issue with the other operators code.
