A good example is the difference between polymeres and aluminium. Polymeres have low E-Modules (in the range of a few GPa) where aluminium has a E-Module of 70GPa. When cutting polymeres, the main problems are melting and smearing of the material, when using the same parameters as for aluminium. | A good example is the difference between polymeres and aluminium.

In the next two plots, you can see how cutting speed, feed per tooth and the resulting revolution speed and feed rate interact. | |||
The limits of the plot are also the limits of our machine. You will notice, that it is not possible with our setup to reach higher values for f_z than 0.35 and the cutting speed is limited to about 600m/min - which is only useful in wood anyways. | |||
[[Datei:Drehzahl.jpg|center|frame|The breaks on x-axis are intentional and are taken from Sorotec's datasheet for end-mills. They resemble the cutting speeds for materials we can work with.]] | |||
[[Datei:Vorschub.jpg|center|frame|In this plot, only a single flute cutter was taken into account, as it results in the highest f_z possible. Using more flutes results in a lower f_z!]] | |||
