Enter cutting speed, diameter and feed per tooth or revolution. The calculator returns spindle speed, linear feed and an estimated material removal rate.
Formula and terminology reference: Sandvik Coromant.
Table feed follows from spindle speed, active tooth count and feed per tooth fz.
For these operations linear feed is calculated from feed per revolution fn.
Compare the result with the tool catalogue, setup rigidity and machine limits.
