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)

And here is some code from an L20 milling a .375 hex on a .500 bar. The attached print shows Point 1,2,3 ect (P1,P2 ect in the program)
