G112

[CatCAD]

Hello! I apologise in advance if this is a stupid question, but I have hit a stumbling block! I am trying to use codes G112 and G113 on a Fanuc O-T operated lathe. But when I enter the codes it comes up with Undefined code! What am I missing, as I am sure it should be able to use these commands. Any help you can provide will be greatfully recieved.

Many Thanks

g112 and g113 I believe are optional interpolation codes. Check the manual to be sure though.

Try G12.1(G112), and if it is still not working check your machine parameter.

I have tried 12.1 and it still does not work! I am new to this lathe and fanuc O-T. What machine parameter should I be looking at?

Many Thanks for your help

You don't have the Polar Interpolation option, It is a 9000 parameter that Fanuc will charge you about 2500.00 bucks to come in and turn it on. I do not have that particular one or I would givie it to you. But some one on this sight may have it.
Do you have the live tooling with a programable C axis? depending on the MB some of those types of machines come with the Polar interp standard and othrs it is an extra option

Hello Bluesman!

Yes I have the Live Tooling with a programable C-axis. Is there somewhere that I can check if this 9000 parameter is included on my machine?

or

If any one does know of said 9000 parameter ..... and would be willing to share I would be extreemly grateful.

Thanks again
