What to enter
| Input | Meaning and units |
|---|---|
| Spindle speed (rpm) | Enter spindle speed in rpm; use the same basis as the other measurements. |
| Engaged teeth (1) | Enter engaged teeth in 1; use the same basis as the other measurements. |
| Feed per tooth (mm/tooth) | Enter feed per tooth in mm/tooth; use the same basis as the other measurements. |
Understanding your result
Read Programmed feed rate (mm/min) in the units and model stated on this page. The formula feed=rpm*flutes*chip defines the relationship; measurement accuracy and model applicability are separate from numerical precision.
Common mistakes
- Mixing input units or changing the physical meaning of a variable without changing the model.
Check your calculation
- Use the worked example as a known reference case, then change one input at a time and check the direction and units of the response.
