    Hello everybody

    I am newbie on a Fanuc controller Oi-Td and I already have a problem with the cutting radius compensation. I write in the first positioning block G42, afterwards I proceed with G1 and still G42 is suddenly deactivated in the next block.

    Has anybody had that problem before and can help me out?

    Thank you in advance

    How do you know that G42 is not active?
    It should stay active until you deselect it with G40.
    The G42 is of course not visible for all new y x values.

    I see the problem in the traverse path that follows without cutting radius calculation- so instead processing e.g. with 1.5mm in z is runs with 1.9mm so hence it ignores my 0,4 cutting radius compensation.
    I have found the error: I am only allowed to drive in the direction in which I approach the G42 command. That’s how it works at the moment....

    Thank you
