Turn an ellipse?

[hmc710]

I had read somewhere that the Tornados will turn shapes other than just diameters such as ellipse or even a hex. One of the manuals shows a hex being machined, but there was an optional tool holder to syncronize with the spindle. Can the standard Tornado do this? Fanuc O-T control
Thanks,

I have the 21 iT control and I have also heard that other shapes than round can be achieved with this machine but my manual has nothing about it in it's content.Being able to make hexes would be tremendous!

Next time I have some spare time I am going to give it a try. I would think it would be like a threading cycle to sync the tool to the spindle. Then perhaps something like a pecking cycle on the x axis. Would take some math layout to coordinate x travel with rotation.

You would think it would have a G code or a canned cycle where you enter G whatever and then the hex size you need a bit like a treading code.?

From what I can remember the manual contains information about other fanuc controls not just O-T. Would you need live tooling to make a hexagon? The machine would have to have spindle orientation.
When I have machined an ellipse on OT and 21iT I have always done it from egdecam.
