Abstract
A double-sided, indexable face milling insert, including an upperside, an underside, and a neutral plane (NP) parallel to the upperside and the underside, the neutral plane forming a right angle with a geometrical center axis (C). A plurality of indexable cutting edges are formed along circumferential borderlines in transitions between a number of clearance surfaces and the upperside as well as the underside. Each cutting edge includes a chip-removing main edge and a surface-wiping secondary edge, the secondary edge forming an obtuse angle with the main edge in planar view. A corner clearance surface extends between and connects each pair of upper and lower secondary edges, the corner clearance surface including first and second part surfaces which each form an acute angle (η) in side elevation view with respective reference planes (RP) parallel to the neutral plane.
