Abstract:
An end mill includes a plurality of teeth and flutes. The teeth and their associated flutes include one or more correlated physical parameters. One such correlated parameter is that, at an axial location in a front half of an effective cutting length, at least one tooth of the plurality of teeth has a rake angle smaller than an average rake angle value of the plurality of teeth, and, at the same axial location, a flute preceding each such tooth has a helix angle larger than an average helix angle value of the plurality of flutes.

Claim (Index 1):
A finish end mill configured for rotating about a central rotation axis (A R ) defining opposite axially forward and rearward directions (D F , D R ), and opposite rotational preceding and succeeding directions (D P , D S ), the preceding direction (D P ) being the cutting direction, the end mill comprising:\n a shank portion; and a cutting portion extending forward from the shank portion to a cutting end face; the cutting portion comprising:\n a diameter (D E ); \n an effective cutting length (L E ) greater than 2.5D E ; \n a plurality of integrally formed teeth; and \n a plurality of flutes alternating with the plurality of teeth, each flute having a helix angle and a flute depth; \n each tooth comprising:\n a rake surface; \n a relief surface succeeding the rake surface and having a relief surface width measurable in a plane perpendicular to the rotation axis (A R ); \n a cutting edge formed at an intersection of the rake and relief surfaces; \n a relief edge spaced apart from the cutting edge and formed at an intersection of the relief surface and a flute surface of the flute succeeding the tooth; and \n a tooth area defined between a first radial line extending from the cutting edge to the central rotation axis and a second radial line extending from the central rotation axis to a nadir of the succeeding flute; \n wherein at an axial location in a front half of the effective cutting length:\n at least two of the teeth have different radial rake angle values, at least some of the different radial rake angle values being different from all other non-identical values by 2\u00b0 or more; and, \n the flute depth of each flute increases with increasing distance from the shank.
