Calculator Information
Details about the Feed Rate calculator
Description
Calculates the table feed (feed rate) based on the feed per tooth, spindle speed, and number of flutes.
Formulas
For both metric and imperial:
Vf = n × z × fz
Units: mm/min
Alternative using feed per revolution:
Vf = n × fn
Where fn = Feed per revolution = z × fz
Parameters
- n: Spindle Speed (RPM)
- z: Number of teeth (flutes)
- fz: Feed per tooth (mm/tooth)
- fn: Feed per revolution (mm/rev)
- Vf: Table Feed (Feed Speed) (mm/min)
Notes
Use chip load recommendations from catalogs carefully, considering Chip Thinning Factor for non-90° cutters or when ae < r.
