Selecting the speed

The correct speed is an important factor for milling. The speed determines the cutting speed by
which the cutting edges cut the material. By selecting the correct cutting speed, the service life
of the tool is increased and the working result is optimized.
The optimum cutting speed mainly depends on the material and on the material of the tool. With
tools (milling cutters) made of hard metal or ceramic insert it is possible to work with higher
speeds than with tools made of high-alloy high speed steel (HSS). You will achieve the correct
cutting speed by selecting the correct speed.
In order to determine the correct cutting speed for your tool and for the material to be cut you
may refer to the following standard values or a table reference book (e.g. Tabellenbuch Metall,
Europa Lehrmittel, ISBN 3808517220).
The required speed is calculated as follows:
V
----------- -
n =
 
d
-1
n = speed in min (revolutions per minute)
V = cutting speed in m/min (meter per minute)
d = tool diameter in m (Meter)
