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 |
How do you calculate feed and speed for CNC?
Feed Rate = N x cpt x RPM
Where: > N - number of cutting edges (flutes) > cpt - chip load (chip load per tooth) is the amount of material, which should be removed by each tooth of the cutter as it rotates and advances into the work.
What speed should CNC spindles be for 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 feed and speed of CNC cutting?
Feed rate refers to how fast the machine moves laterally through your material, measured in inches per minute (IPM). Speeds are referring to the spindle/router rotations per minute (RPM). Increasing the spindle speed (RPM) doesn't automatically mean that the feed rate should go up or down.
