What to enter
| Input | Meaning and units |
|---|---|
| Spindle speed (rpm) | Enter spindle speed in rpm; use the same basis as the other measurements. |
| Feed per revolution (mm/rev) | Enter feed per revolution in mm/rev; use the same basis as the other measurements. |
Understanding your result
Read Penetration rate (mm/min) in the units and model stated on this page. The formula feed=rpm*feedPerRev 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.
