    Default Questions regarding Citizen A20 and Citizen M20

    Just took on a new position programming several Citizen machines. I've programmed everything they have in the past. The only two that are new to me is a A20 which is around a year old and a M20 which is a 1998 model.
    Looks like the A20 is a Fanuc control. With the M20 I'm not familiar with 3 channel programming.
    Could someone she'd some light on this and maybe a sample program.
    Thanks

    I'd suggest you purchase WinCNC or similar. The older M-series machines may take the older G700 codes.

    If you have already programmed the "L" series machines you won't have an issue with the M20.
    $1 is what your used to just tool numbers are different. (T11 - T18 instead of T1 - T9)
    $2 is the turret, T20 - T29, You have more tools and they can be used on either spindle.
    $3 is pickoff or support during cutting.
    THEN, you can go way beyond what your used to, like putting 3 tools in the cut at the same time, pinch turning, Pinch turning while supporting with the sub spindle.....
