Abstract
A family of cutting inserts includes a plurality of different inserts, each having a different geometry. Each insert of the plurality of different inserts is adapted to be mounted in a common insert-receiving pocket on a toolholder of a milling cutting tool so that an outer diameter generated by the milling cutting tool is the same, regardless which insert of the plurality of inserts is mounted in the pocket.

A family of cutting inserts, comprising a plurality of different inserts, each having a different geometry, wherein distances between cutting edges and corresponding insert supporting surfaces are selected for each insert of the plurality of different inserts so that each insert is adapted to be mounted in a common insert-receiving pocket on a toolholder of a milling cutting tool so that a largest outer diameter by rotation of the milling cutting tool about a longitudinal axis of the milling tool is the same, regardless which insert of the plurality of inserts is mounted in the pocket, wherein
- at least a first one of the plurality of inserts has a plurality of sides when viewed in plan, each side of the first one of the plurality of inserts comprises a cutting edge, the cutting edge on each side of the first one of the plurality of inserts is separated from the cutting edge on an adjacent side of the first one of the plurality of inserts by a corner, and each cutting edge on each side of the first one of the plurality of inserts defines an arc of circle,
- at least another one of the plurality of inserts is substantially circular when viewed in plan,
- the largest outer diameter being formed by the first one of the plurality of inserts a point on a cutting edge of the first one of the plurality of inserts that lies between and remote from endpoints of the arc of the circle defined by the cutting edge, and
- each of the inserts comprises at least two planar side insert supporting surfaces.
A family of cutting inserts, each cutting insert in the family of cutting inserts having a bottom supporting surface and an axis of rotation and, arranged around the axis of rotation, a plurality of side insert supporting surfaces and a plurality of cutting edge portions corresponding to each of the plurality of side insert supporting surfaces, the cutting edge portions for each insert being generally convex and the cutting edge portions for at least some different inserts in the family having different curvatures, wherein, for each cutting, edge portion, a first plane parallel to the axis of rotation and tangent to the cutting edge at a face contact point on the cutting edge portion is disposed at a predetermined distance from a parallel second plane extending through the axis of rotation and rotated at a predetermined angle relative to a third plane intersecting, a corresponding side insert supporting surface along a line substantially perpendicular to the axis of rotation.
A cutting insert comprising at least four cutting edges and a corner between pairs of the cutting edges, the cutting insert being indexable to at least four positions, each cutting edge lying along an arc of a respective circle, wherein a first line extending through a centerpoint of a respective one of the cutting edges and a radial center of the respective circle of the respective one of the cutting edges forms a non-zero angle with a second line extending through the centerpoint of the respective one of the cutting edges and a center of rotation of the insert.
