Abstract:
An end mill for shouldering and/or slotting applications includes at least one tooth including a cutting edge. The cutting edge includes a first sub-edge extending rearwardly from a cutting end face and a second sub-edge extending rearwardly from the first sub-edge. An angle transition intersection defines where the first sub-edge ends and the second sub-edge starts. The angle transition intersection is located generally between 20% to 75% of an effective cutting length from a cutting end face and more specifically at a location within the general location where there is an increase in the rake angle and/or a significant increase in the helix angle of the cutting edge.

Claim (Index 1):
An end mill having unitary one-piece construction and configured for configured for shouldering and/or slotting applications and 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 opposite rear and cutting end faces, and a peripheral surface extending therebetween; a shank portion extending forward from the rear end face; and a cutting portion extending forward from the shank portion to the cutting end face; the cutting portion comprising:\n a diameter (D E ); \n an effective cutting length (L E ); \n a plurality of integrally formed teeth; and \n a plurality of flutes alternating with the plurality of teeth; \n at least one tooth of the plurality of teeth comprising:\n a rake surface; \n a relief surface succeeding the rake surface and having a relief surface width which is measurable in a plane perpendicular to the rotation axis (A R ); and \n a cutting edge formed at an intersection of the rake and relief surfaces; \n the cutting edge comprising:\n a first sub-edge extending rearwardly from the cutting end face; \n a second sub-edge extending rearwardly from the first sub-edge; and \n an angle transition intersection defining where the first sub-edge ends and the second sub-edge starts; \n the first sub-edge comprising:\n a first radial rake angle; \n a first helix angle; and \n a first relief angle; \n the second sub-edge comprising:\n a second radial rake angle; \n a second helix angle; and \n a second relief angle; \n the angle transition intersection comprising:\n an intersection rake angle; \n an intersection helix angle; and \n an intersection relief angle; \n wherein, for the cutting edge:\n the angle transition intersection is generally located in a general location GL which is an axial distance from the cutting end face defined by the condition: 0.20L E \u2264GL\u22640.75L E ; and \n the angle transition intersection is precisely located at a precise location PL within the general location GL, the precise location PL being defined as a closest axial location to the cutting end face, within the general location GL, which fulfills at least one of:\n a first condition wherein the intersection rake angle is greater than all of the rake angles which are closer to the cutting end face; and \n a second condition wherein the intersection helix angle is at least 5% greater than a first helix angle directly preceding the intersection helix angle.
