I have no problem calculating the deg/min feed on a 4th axis when it is a path along the same X on a vertical mill. Now with a helix, the circumference is going to be longer. Is there a constant value that I can use to accommodate for the length of helix? Also when posting in Gibbs with the same parameters, the posted feed rate is half what I calculate....not sure why.
any insight on this would be great.
