PUTTING IT INTO PRACTICE
Drilling Material Removal 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 |
|---|---|
| Hole diameter (mm) | 10 |
| Axial drilling feed (mm/min) | 100 |
| Result | 7.853982 cm³/min |
- Check the input labels and enter the example values above.
- Apply the relationship: Removal rate = π × diameter²/4 × feed/1000.
- The result is 7.853982 cm³/min, rounded for display.
How to interpret your result
Nominal cylindrical hole removal; peck cycles and point geometry 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 drilling material removal rate calculator useful?
Find nominal drilling removal rate from hole diameter and feed. Nominal cylindrical hole removal; peck cycles and point geometry are excluded.
How do I use the drilling material removal rate calculator?
Enter hole diameter (mm), axial drilling feed (mm/min). The result updates automatically. Use the units shown beside each input; the example values illustrate the method.
Which formula does this calculator use?
Removal rate = π × diameter²/4 × feed/1000.
What should I check before using the result?
Nominal cylindrical hole removal; peck cycles and point geometry 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.
