    Unhappy Okuma cadet 4020 mill m&g codes

    I cannot get this machine to run a M98Pxxxx sub program in EIA.
    Machine skips right over the M98 Pxxx command and goes to the next position.
    It also does not recognize the G98 command when drilling tapping. I need to jump over clamps ect.
    It alarms out with alarm# 425 Alarm B unusable g code 62.

    Does anyone have a list of M&G codes for this machine?

    Thanks, Al

    You are programming with Fanuc format ... the OSP is different :

    M98 P1234 would be CALL O1234

    No G98 ... you need :

    G71 Z ( this is your initial plane ... this block is prior to your canned cycle call )
    M53 is G98
    M54 is G99

    Hope this helps ...

    What is the OSP command that would work the same as the Fanuc M99?
    I want the program to keep running untill I stop it.
    This is a new (old) machine and I would like to keep it cycling the program it's going to be running for a day or two to see if there are any problems with it.

    Thanks, Al

    M99 for Okuma

    The command RTS is used at the end of a subprogram ... like M99 on the Fanuc.

    RTS works fine for the sub prg. I want to keep running the main program, without having to press cycle start each time. RTS in place of M30 in the main alarms out.
    Thanks again, Al

    right before the end of the program. Enter this exactly;

    GOTO N100

    on the second line, at the top of the program enter this;

    N100.

    This will loop the main.
