Speeds and Feeds for Endmills
I am looking for some guidelines on determining depth of cut and feed rate when using end mills for side milling. I have found some references that suggest a depth of cut of 1/2 the cutter diameter is about the maximum. However, when side milling, say a surface that is 1.75" tall with a 1.5", 6 flute end mill, how do you determine the depth of …

Ball Nose vs Flat End Mill
For example, if you are making a 0.050″ depth of cut with a 1/4″ ball nose end mill, the feed rate would be around 10 IPM. – Adjust the feed rate based on the rigidity of the setup. A more rigid setup can handle higher feed rates, while a less rigid setup may require lower feed rates to avoid chatter.
