    Hi Hector

    It is because C axis is controlled in degrees per minute, so if you diameter is small it has to move many revolutions to maintain a the same linear feed in mm/per minute.

    On a diameter of 114.65mm the feed is the same in degrees per minute
    as in mm per minute, but higher if smaller and lower if bigger.
    That is because one turn (360 degrees) divided with pi is 114.65mm.
    Divide with 25.4 and you get it in inch.
