Calculate the RPM and feed of the milling machine based on the milling cutter diameter, number of teeth and cutting speed

Also calculation of the RPM of the drilling machine based on the drill diameter and cutting speed

Recommended cutting speeds based on the material to be milled and milling cutter type

Material Milling cutter type Cutting speed
Steel HSS-Cobalt 25 - 30 m/min.
Hardmetal inserts 100 - 160 m/min.
SS HSS-Cobalt 8 - 18 m/min.
Hardmetal inserts 100 m/min.
Aluminium HSS-Cobalt 70 - 100 m/min.
Hardmetal inserts 200 m/min.

Recommended cutting speeds based on material to be drilled and drill type

Material HSS drill HSS drill+TiN FullHardMetal drill
Unalloyed steel 35 m/min. 45 m/min. 80 m/min.
SS 10 m/min. 15 m/min. 28 m/min.

For the calculation of the feed speed following feed rates for each tooth are applied based
on the milling drill diameter

diameter (mm) feed for one tooth
2 - 4 0,002
5 - 7 0,012
8 - 13 0,03
14 - 19 0,07
20 - 30 0,08
