For example, if you are making a ″ depth of cut with a 1/4″ ball nose end mill, the feed rate would be around 10 IPM. Adjust the feed rate based on the rigidity of the setup. A more rigid setup can handle higher feed rates, while a less rigid setup may require lower feed rates to avoid chatter.

For the full scale mill, specific power is multiplied by the feed rate to get the net mill power. This must then be increased by the anticipated mechanical inefficiencies (bearing/gear friction losses and possible speed reducer losses) as well as electrical losses, in order to arrive the gross mill power.

One can argue the f50 is a more realistic value since balls wear and the average ball size might be closer to half the maximum. Then the multiple would be closer to 13 times the maximum particle size fed to the ball mill. A f80 = 6 mm would need a ball size of 75 mm.
