You want that feed rate based on the machine's needs to change degree output to the correct method needed. Feeding at 50 deg a minute depending on the part is going to be a nightmare in so many ways it is not even funny. Might think if you want inverse time for the output verses degree per minute. Kinematics need to be taken into account and unless you got a 31i or a 840D control you want the post to start doing some of the heavy lifting here.
