Machining a part right means matching spindle speed and feed to the material. The cutting speed (surface meters per minute) sets the RPM for a given tool diameter; the feed rate is RPM times chip load per tooth times the number of teeth. Too fast burns the tool; too slow rubs and work-hardens. The material removal rate is your productivity.

Governing equation

n = \frac{1000 V _{c}}{π D} = \frac{1000 \cdot 300}{π \cdot 10} = 9549 rpm, v_{f} = n z f_{z} = 1910 \frac{mm}{min}

Reading this result: Feed rate is RPM times chip load times flute count, so adding flutes or feed lifts throughput here to about 38.2 cm³/min without changing the surface speed.
