PUTTING IT INTO PRACTICE
Turning Feed Rate: a worked example
The values below are an illustrative example, not a recommendation. Replace them with measurements or assumptions that match your question.
| Input | Example value |
|---|---|
| Feed per revolution (mm/rev) | 0.2 |
| Spindle speed (rpm) | 500 |
| Result | 100 mm/min |
- Check the input labels and enter the example values above.
- Apply the relationship: Axial feed = feed per revolution × rpm.
- The result is 100 mm/min, rounded for display.
How to interpret your result
Steady nominal turning feed; acceleration, tooling and machine capacity are excluded.
Choose cutting speeds and feeds from suitable tooling and material guidance. These tools translate quantities rather than selecting safe cutting conditions. Effective diameter, engagement, machine limits and setup time need separate attention.
Frequently asked questions
Does the spindle-speed calculation recommend a cutting speed?
No. You supply the cutting speed. The tool converts it and a diameter into revolutions per minute.
When is the turning feed rate calculator useful?
Convert a turning feed per revolution into linear travel rate. Steady nominal turning feed; acceleration, tooling and machine capacity are excluded.
How do I use the turning feed rate calculator?
Enter feed per revolution (mm/rev), spindle speed (rpm). The result updates automatically. Use the units shown beside each input; the example values illustrate the method.
Which formula does this calculator use?
Axial feed = feed per revolution × rpm.
What should I check before using the result?
Steady nominal turning feed; acceleration, tooling and machine capacity are excluded.
How are results rounded?
Scalar numbers display up to six decimal places, with scientific notation for very large or small values. Text, fraction, date and schedule outputs use the format described on the tool. Intermediate calculations use JavaScript floating-point arithmetic. Keep sensible precision for your measurements.
