Patent ID: 6942433

Claim:
A milling tool for milling workpiece surfaces, the milling tool having a rotational axis and comprising: one or more cutting segments, each with a cutting edge geometry including a main cutting edge, a cutting corner, and a secondary cutting edge; said cutting segments being formed such that a generatrix of an envelope curve described by a rotation of the milling tool includes a cutting corner portion, a first segment adjoining said cutting corner portion, and a second segment adjoining said first segment; said first segment having a projection length of at least 1 mm, in a projection thereof onto the axis of rotation, lying nearest to the rotational axis at a beginning point bordering said cutting corner, and lying farthest from the rotational axis at an end point distal from said cutting corner, and wherein a tangent at each point within said first segment encloses an angle α 1 in a range of 0° to 5° with a parallel to the rotational axis; said second segment having a projection length of at least 1.5 mm, in a projection thereof onto the axis of rotation, lying farthest from the rotational axis at a beginning point thereof bordering on said first segment, lying nearest to the axis of rotation at an end thereof, and wherein a tangent at each point of said second segment encloses an angle α 2 in a range from >0° to 3° with the parallel to the rotational axis and the angle α 2 increases progressively toward the end of said second segment; and said projection length of said second segment being at least 1.5 times greater than said projection length of said first segment.
