Data Source and Methodology
All calculations are based on the standards and formulas provided by the Machining Handbook, 2023 Edition. View source.
The Formula Explained
The spindle speed (RPM) is calculated using the formula: RPM = (Cutting Speed × 1000) / (π × Tool Diameter)
The feed rate (mm/rev) is calculated using the formula: Feed Rate = RPM × Feed per Tooth × Number of Teeth
Glossary of Terms
- Tool Diameter: The width of the tool used in the machining process.
- Cutting Speed: The speed at which the cutting edge of the tool moves across the material.
- Spindle Speed: The rotational speed of the tool.
- Feed Rate: The distance the tool advances during one revolution of the spindle.
Frequently Asked Questions (FAQ)
How do I use the machining calculator?
Enter the tool diameter and cutting speed to calculate the optimal feed rate.
What is cutting speed?
Cutting speed is the speed at which the cutting edge of the tool passes over the surface of the workpiece.
What units should I use?
Ensure all measurements are in millimeters and meters per minute for consistency.
What is spindle speed?
Spindle speed is the speed at which the tool rotates in the spindle, measured in revolutions per minute (RPM).
How can I ensure accurate results?
Double-check your input values and ensure the tool and material are compatible with the provided parameters.
