Abstract
It is the object of the present disclosure to provide an improved end mill that can be easily manufactured, reduces cutting forces on the driving tool, limits chatter at high rotation speeds, has better stability, produces smoother cutting surfaces, and has less natural resonating frequencies while in use to permit operation of the end mill over a wider range of operating conditions. The end mill is equipped with a series of sinusoidal cutting edges with a single long pitch arranged regularly or irregularly along the circumferential cutting surface. In another embodiment, the pitch, the cutting angle of the datum line of the sinusoidal cutting edges and the amplitude of the sinusoidal function can be varied.
