    Citizen A32 Rotary milling.

    Does anyone have a functional program example of C axis rotary milling I could draw from to use on my Citizen A32 machine?

    Thanks!

    This is from a L20, but it should basically be the same.

    This is for milling a Torx (hexalobe) in the sub spindle. The business end of things are

    M48C0 (starting index angle)
    X0 (because it was done in the sub and the middle was pre-drilled. This could be above stock diameter if you want to be safe)
    G12.1D0E=C (activate polar milling)
    G17 (select g2/g3 plane)

    ===== Hexalobe milled in sub =====

    M48C0
    X0
    G12.1D0E=C
    G17
    G42G1X.1134Y0F30.
