What should my CNC feed rate be?
Materials | Feedrate for various tool diameters [mm/min] | |
Plywood | 1150 | 3680 |
MDF | 1323 | 4232 |
Soft plastics | 960 | 3360 |
Aluminium | 800 | 2560 |
What RPM is needed for CNC cutting wood?
A good rule of thumb for RPM (when using the HF500) is to keep the setting at 15,000 rpm or higher for cutting woods. You will have more cutter speed which will make the tool cut easier and should provide a better finish.
What is the cutting speed of wood?
For wood, the standard cutting speeds are already very high: for the softest wood species, a cutting speed about 60 m s–1 is normal and 40 m s–1 for the hardest wood species. In sawing process, a cutting speed of 70 m s–1 is not unusual.
How do you calculate cutting speed and feed?
Milling Formulas
1
Speed (RPM) = (SFM x 3.82) / D.
2
Feed (IPM) = RPM x FPT x Z.
3
SFM (Surface Feet per Minute) = (RPM x D) / 3.82.
4
IPT (Inches per Tooth) = (IPM / RPM) / Z.
5
MRR (Cubic Inches per Minute) = IPM * WOC * DOC.
6
AFPT (@ less than 1/2 dia. WOC) = IPM x sqroot of (D / WOC)
7
HP (Horsepower Consumption) = MRR x mf.
