Enter your parameters in the form to calculate feeds and speeds.
Cutting speed and feed values are typical starting-point values taken from Autodesk's "Fundamentals of CNC Machining" training guide (2014), Chapter 3, Tables 5–9. They represent conservative, reliable parameters suited for prototype and short-run production.
Actual optimal feeds and speeds depend on many factors not captured here, including:
These values are for educational and preliminary planning purposes. Always start conservatively, observe the cut, and adjust based on actual results. For production machining, consult your tooling supplier's data and run test cuts.
The source document covers milling operations primarily. Lathe SFM values are derived from the milling table using the same formulas (same physics, different diameter reference). Verify lathe parameters with your tooling supplier.
Abeyant Maker makes no warranty regarding the accuracy or fitness for purpose of any calculated values. Users assume full responsibility for verifying parameters before machining.
