CuTTING SPEED
Cutting Speed is the speed of the workpiece surface relative to
the edge of the cutting tool during a cut, typically measured in
surface meters per minute. You can calculate Cutting Speed by
entering the Diameter of the tool or material you’re using and the
RPM (Spindle Speed).
Cutting Speed – Milling
Calculate the Cutting Speed for a mill using a 15 mm tool
running at 1 250 RPM (Spindle Speed):
