Feeds and speeds start with surface speed. Use the RPM calculator to turn a recommended SFM and tool diameter into a spindle speed, then use the feed rate calculator with your chip load and flute count to find the table feed. The chip load, feed per tooth, and table feed calculators work the same relationship from different directions, which helps when you are checking an existing program.

Metal removal rate and time to machine give a quick picture of productivity. Use them to compare two strategies or to estimate a cycle before programming. Treat every result as a starting point, then adjust to the sound and chip shape of the real cut.
