CNC Milling calculating-rules
RPM [Revolutions per Minute]
- RPM = M / Tooldiameter
| Material | RPM |
|---|---|
| Polrycarbonate | 20000 |
| Aluminium | 10000 |
| Nylon | 7000 |
| Steel | 5000 |
- A typical RPM could be 3000
Feed-rate [mm/minute]
- Feedrate = K * ToolNumberOfTeeth * RPM
- K is a teeh-strok in the material
- K is usally 0.05
- K is maximum of 0.2
- K defines how fine the cut should be
- A typical Feed-rate could be 300
Plunge-rate [mm/minute]
| Små fräs (3mm) | Plunge-rate = 20% av Feed-rate |
- No more than 100
