CNC Feeds and Speeds by Material
Feed in inches per minute = RPM × flute count × chip load in inches per tooth.
Feed in inches per minute = RPM × flute count × chip load in inches per tooth.
What this tool does
Feed in inches per minute = RPM × flute count × chip load in inches per tooth.
Review the output before the next step
The function operates on the supplied source and listed assumptions. Confirm the output format fits the receiving workflow before copying it into a production record. The fields available on this page are Spindle speed (RPM), Flutes, Chip load (in). Feed in inches per minute = RPM × flute count × chip load in inches per tooth.
How it works
Feed in inches per minute = RPM × flute count × chip load in inches per tooth.
Inputs
| Field | Example | Definition |
|---|---|---|
| Spindle speed (RPM) | 6000 | Measure spindle speed (rpm) in the displayed unit. Convert the source measurement before entry if it uses another system; a changed label does not perform a unit conversion. |
| Flutes | 2 | Use the source quantity represented by flutes. Keep the counted population fixed and avoid mixing a unit value with a period total. |
| Chip load (in) | 0.004 | Use the source quantity represented by chip load (in). Keep the counted population fixed and avoid mixing a unit value with a period total. |
Step-by-step guide
Prepare the source
Supply Spindle speed (RPM), Flutes, Chip load (in). Keep the original material so the output can be compared with it.
Use CNC Feeds and Speeds by Material
Check Spindle speed (RPM), Flutes, then select Use CNC Feeds and Speeds by Material.
Use the result
Compare the cnc feeds and speeds by material result with the unchanged source before copying or downloading it.
When to use it
Feed in inches per minute = RPM × flute count × chip load in inches per tooth. The function operates on the supplied source and listed assumptions. Confirm the output format fits the receiving workflow before copying it into a production record.
