Calculating CNC Machining Feeds and Speeds

The information presented in this blog post is for educational purposes only. It should not be used for engineering design or relied upon as engineering advice.

The EngineeringPaper.xyz calculator below calculates the required feeds and speeds for CNC milling operations. Even though the example values are provided in U.S. customary units, the sheet will also work with SI units by changing the specified units in the input and output fields.

This sheet may also be opened in a separate tab.
