Abstract:
1. 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.
