Hi
I work on a lathe at work that has live tooling but it has a option of Cartesian-to-polar interpolation, programming x and y on the lathe which converts it to x and c. but the option is not installed. does anyone know or have a macro that can do Cartesian-to-polar interpolation ?
thanks

I think what you need is G12.1/G112, It already build in the machine.

I tried g12 and g12.1 but they didnt work. never tried g112
have to try it mon

[CNCRim]

What is the branch of your machine and what try of control?

If you did tried G12.1, then I assume G112 will trip same alarm. I suspect the parameter is not set on for Polar or the M-code is need before excute G12.1.

it is a colchester CNC650 and has a fanuc 10t controller
thanks

I tried G12, G12.1 G112 and I get a alarm (ps010).

in the g-code list in the users manual does not have a g12 or g12.1 in it but there is a section in the manual about g12.1

Yeah, I think you need to call application support and ask them how to turn milling polar. Then the machine should fine, G12.1 is standard for full c-axis.
