CNC Feeds & Speeds provides mathematical calculators and technical reference information. The outputs are starting calculations only.
Verify before production
Verify toolmaker cutting data, material grade and condition, cutter geometry, machine RPM and feed limits, workholding, tool stick-out, coolant and the intended engagement. Perform a controlled test cut before production use.
No guarantee of outcome
The site cannot account for every physical variable in a CNC machine setup. A mathematically correct result may still be unsuitable for a particular machine or workpiece.
Responsibility
The user is responsible for the final machining process, program review and safe operation of the machine.
