Solid Carbide machining recommendations
Formulas
rpm = sfm * 3.82 / tool diameter
rpm = (m/min * 1000) / (3.14 * tool diameter)
feed per min = feed per tooth * number of teeth * rpm
Machining tips
1. For profiling-finishing cut - use 4 or 6 flute mill.
2. For slotting - use 3 flute mill for semi-roughing and higher feed rate.
Use a roughing mill for maximum chip removal. Use a 2 flute mill for long
chips (soft material).
3. For plunge-slot operation - use 3 flute mill for higher feed rate and 2 flute
mill for soft material.
4. For profiling-roughing cut - use roughing mill for rapid material removal
and higher feed rate.
5. For contour-finishing - use 2 or 4 ball nose mill.
6. For slot-contouring - use 2 flute ball nose for maximum chip removal.
Use 4 flute ball nose for finishing.
7. For profiling thin material - use 6 flute mill.
8. Climb milling is preferred in CNC machines.
9. For Aluminium machining use 6, 8 flute positive rake mill for finishing and a 2
flute short mill for slotting.
