    Okuma VTR-350A

    Hello World

    I am using carousel lathe with OSP S300 and I am having problems with milling operations.

    Sometimes machine makes weird toolpath, only with milling operations.

    it happens only when I am tring to make a hole or axel but it doesnt make pefect circle. Hole or axel being oval.


    I am using mastercama to make program...I can NOT program manuel on the machine.

    Machine is never bin crashed (was serviced a mount ago)

    lathe works fine.


    Thank you.

    You need to supply better/more info...
    The CNC code...
    What the machine did...
    What it was meant to do...
    .... it could be operator error, programmer error,or even a post processor not written correctly.

    ... it may need to be put into the Mastercam forum... or approach the post creator to get proper programming instructions (or post correction)

    No one can see your problem
    ... a circle huh... what plane ?
    Did the machine do what the NC code told it to do ?
    If it did, then it is a programming, or post issue.

    More than likely a problem with how it is programmed ?
    Is it a dedicated post processor, customised to that machine?

    The code AND a pic would be a good start.
