FEED RATE
Feed Rate is the speed of the cutting tool’s movement relative
to the workpiece as the tool makes a cut. You can calculate
Feed Rate given values for Cutting Feed and RPM (Spindle
Speed). If you don’t know the Cutting Feed, you can calculate
Feed Rate with Feed per Tooth (Chip Load), Number of Teeth
and RPM.
Feed Rate – Based on Cutting Feed and RPM (for Turning)
Calculate the Feed Rate if you are turning a 25 mm steel
round stock down with a Cutting Feed of 0.80 millimeters
per revolution (mm/rev) and a rotational speed of 900 RPM
(Spindle Speed):
