Abstract
Provided is an endmill. The maximum spindle speed, per one minute, of a main spindle to which the endmill is attached is Smax. The number of teeth of the endmill is N. The outer shape of the endmill is Da. The natural frequency at which vibrations at the end of the endmill reach a maximum level is ω1. ω1 and/or N are set so that when the diameter-direction infeed amount of the endmill is set to Rd: i) ω1×60/N×6<Smax, if Rd is at least 4% of Da; and ii) ω1×60/N×3<Smax, if Rd is less than 4% of Da.
