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 |
