    You need to tell everyone a lot more what you are programming.
    How big is the piece diameter, how long does it stick out of the jaws, what is the material?
    You could have all kinds of reasons for vibration.
    Please give us the program, especially RPM, dedth of first cut if you use the
    G76 cycle.
    Better show the whole program.
