    Default Drilling holes in x-y plane on rotary table

    In Mastercam X, how would I dill a radial set of holes in a disk mounted in a rotary table rotating around the z axis? I can't find the correct drilling command that will allow the rotary table to rotate around the z axis.

    To be more specific I am wanting to create a CAM based program to drill the holes in an indexing plate I plan to use on my spindexer. My preference is to use the rotary table capability rotating around the z axis rather than moving to the x-y- locations. I also plan to use a similar concept to machine slots in the plate by rotating the rotary table and holding the spindle in a same x/y location.

    Have you tried rotary axis substitution, it is the last section under the parameters tab. Just make sure to put your rotary diameter in the area where it asks for a value.

    if you ar rotating about z, that would be considered a c axis.
    and a radial hole would not be in the xy plane.
    ?????


    if you want to drill holes in the face you might have quicker success using a live tool lathe post and do some minor editing.
    if you want perfect code out of the mill/router side it will required custom post mods

    What is your reason for using a rotary instead of using point to point x-y locations?

    I would just hand write it.
    #500=0
    #501=(NUMBER OF HOLES)
    #502=360/#501(DEGREES)
    x---- y----a0.
    while[#500 LT #501]DO1

    G90G81z---- r------f------
    G91 A=#502
    x0.y0.
    #500=#500+1
    END1
    G90

    BUT THE X/Y POSITIONING SHOULD BE MORE ACCURATE DUE TO THE POSSIBLE ROUNDING IN THE RADIAL COMPUTATIONS(IE: 360/5=51.42857 DEGREES )THE CONTROL WILL ROUND IT UP OR DOWN INCURRING AND ERROR

    I have a large diameter part that is out of the limits of the x on the table. I appreciate the g code solution (I know how to do that) I was looking for a simple CAM solution with MasterCam X rotating around the Z axis (parallel to the tool spindle)
