Abstract
A double-sided cutting insert with orientation-assisting geometry includes identical and opposite first and second main surfaces and a peripheral surface which extends therebetween. The insert further includes a median plane located midway between the first and second main surfaces and opposite first and second clamping recesses opening out respectively to the first and second main surfaces. Projections onto the median plane of at least portions of the first and second clamping recesses are rotationally offset from one another about a central axis.
Claims18
A double-sided cutting insert (12, 112) having orientation-assisting geometry and a central axis (C) around which the insert is indexable, the insert comprising:
- opposite and identical first and second main surfaces (18, 20) and an insert peripheral surface (22) extending therebetween, each main surface (18, 20) comprising a cutting portion (36),
- a median plane (P) perpendicular to the central axis (C) and located midway between the first and second main surfaces (18, 20);
- and
- opposite first and second clamping recesses (26, 126, 28, 128) opening out respectively to the first and second main surfaces (18, 20);
- wherein:
- each clamping recess (26, 126, 28, 128) is elongated in a direction parallel to the median plane (P), along an elongation axis (E1, E2);
- each clamping recess (26, 126, 28, 128) comprises a recess peripheral surface (30a, 30b) which comprises at least one recess abutment surface (32);
- and
- projections onto the median plane (P) of at least portions of the first and second clamping recesses (26, 126, 28, 128) are rotationally offset with respect to one another about the central axis (C).
