How to Use This Calculator
- Enter the chip load (IPT or mm/tooth) from your cutter manufacturer's recommendations.
- Set the number of flutes on the end mill or drill.
- Enter the target spindle speed (RPM).
- Review the calculated feed rate in IPM and mm/min, and feed per revolution.
- Adjust chip load or RPM to keep feed rate within your machine's capability.
