How to: C-Axis mill mode

[Karbure]

Hello,

I'm looking for documentation and exemple to learn how to use the mill mode on a CNC 3-axis Lathe. I'm currently working on a Fanuc iO-TC and I need to make a small flat on the side of a rod.

Hello,

This will usually vary by machine and model as far as M-codes, etc. and installed options.

What make and model lathe do you have?
Does it have cylindrical and polar interpolation options installed?
Do you want to use the side of the end mill (Z-axis tool) or the end of the mill (X-axis tool)?

I'm working on a Hyundai-KIA SKT-21 with a Fanuc iO-TC controller. I never used cylindrical or polar interpolation but think the polar interpolation options is present. Also, for the flat on the side of my rods, I'm looking to use the side of an end-mill (z-axis tool).

I know there's a G/M code to switch mode an refer movement as a Cartesians grid (x, y, z) just like a milling instead of degrees on the c-axis. But I haven't been able to find the documentation on it.

I believe you're referring to Polar Coordinate Interpolation (G12.1). In this mode you program X and Y moves (but address the Y as C). If you can't find it in the manual I'll try to find an explanation for you.
