Fanuc 10T Threading

[SGARCIAM]

Does anyone have a programing manual for Fanuc 10 T. We need a 90 deg pull out for the threading.

I have one back at the shop. What do you need to know? Which G Code? G92? G76? G32?

g76
THANK YOU

Sorry, my manual says nothing about "pullout" angles. I use G32 exclusively. Maybe someone else could help...

On edit....


Best I can come up with is to check machine parameter 6212, change to .1, parameter 6213, change to 89°. It seems you can either have .1 X lead "chamfer" or 89° (not zero X lead or 90°) due to servo response.

Some builders used an M function to turn chamfering on/off in threading cycles. This should be listed with your machine's M-codes if this is the case. I know on some Doosan lathes it's M76 (on) and M77 (off). Old Mori lathes were M23 & M24. This had to be in the block before the G76 command.

If you are using the 2-block G76 call, then the middle pair of values for the P in the first block control pull-out. 00 will be a 90 degree pull-out.

EDIT: The M-code option would be specific to the MB. None are used with the 2-block call that I am familiar with. Our Hitachi uses a single block G76. M24 would be no chamfer (90 degree pull-out), M23 uses what they call thread chamfering. Parameter 155 controls the length of the pull out, Parameter 155 contols the angle it pulls out over that distance.
