Abstract

A cutting insert (10) comprising two opposing end surfaces (2) , a peripheral side surface (14) extending therebetween and a peripheral edge (30) formed at an intersection of each end surface (12) with the peripheral side surface (14) , at least one peripheral edge (30) comprises two minor edges (36) and a cutting edge (32) extending therebetween, a first section (38) of each minor edge (36) extending from the cutting edge (36) generally towards the opposing end surface (12) .

Claims (19)

1. A cutting insert (10) comprising two opposing end surfaces (12) having a first axis (A) passing therethrough, a peripheral side surface (14) extending between the end surfaces (12) and a peripheral edge (30) formed at an intersection of each end surface (12) with the peripheral side surface (14), at least one peripheral edge (30) comprises two minor edges (36) and a cutting edge (32) extending therebetween, the peripheral side surface (14) comprises two minor faces (20) forming each an internal obtuse angle (.beta.) with a major face (18) extending therebetween, with the cutting edge (32) being associated with the major face (18) and each minor edge has a first section associated with a respective minor face (20), the first section extending from the cutting edge (32) generally towards the opposing end surface (12).
2. The cutting insert (10) according to claim 1, wherein the cutting insert (10) has 180° rotational symmetry about the first axis (A).
3. The cutting insert (10) according to claim 2, wherein:

a second axis (B) perpendicular to the first axis (A) passes through the major face (18); and the cutting insert (10) has a symmetry defined by a rotation of 180°
around the second axis (B) plus a 90° rotation around the first axis (A).
4. The cutting insert (10) according to claim 1, wherein:

a second axis (B) perpendicular to the first axis (A) passes through the major face (18); and the cutting insert (10) has a symmetry defined by a rotation of 180°
around the second (B) axis plus a 90° rotation around the first axis (A).
5. The cutting insert (10) according to claim 4, wherein each peripheral edge (30) comprises at least one support edge (34) located opposite a given cutting edge in the direction of the first axis (A).
6. The cutting insert (10) according to claim 1, wherein an identical internal obtuse angle (.beta.) is formed between each minor face (20) and adjacent major face (18).
7. The cutting insert (10) according to claim 1, wherein each minor edge (36) has a second section (40) extending from the first section (38) generally away from the opposing end surface (12), the second section (40) not being associated with the minor face (20).
8. A cutting insert (10) comprising:

two opposing end surfaces (12) having a first axis (A) passing therethrough;

a through bore (16) extending between the two opposing end surfaces (12) and having a bore axis that coincides with the first axis (A);
a peripheral side surface (14) extending between the end surfaces (12); and a peripheral edge (30) formed at an intersection of each end surface (12) with the peripheral side surface (14); wherein:

the peripheral side surface (14) comprises four identical major faces (18) and four identical minor faces (20), each major face (18) having a first end (22) adjacent one end surface (12) and a second end (24) adjacent the opposing end surface (12);

each major face (18) extends between two minor faces (20), each of the two minor faces (20) forming an internal obtuse angle (.beta.) with the major face (18) that extends therebetween;

each peripheral edge (30) comprises two identical opposing cutting edges (32), two identical opposing non-cutting support edges (34) and four identical minor edges (36), each minor edge (36) located between an adjacent cutting edge (32) and a non-cutting support edge (34);

each cutting edge (32) is associated with a major face (18); and each minor edge (36) has a first section (38) associated with a respective minor face (20), the first section (3 8) extending from the cutting edge (32) generally towards the opposing end surface (18).
9. The cutting insert according to claim 8, wherein the cutting insert has 180° rotational symmetry about the first axis (A).
10. The cutting insert according to claim 9, wherein:

a second axis (B) perpendicular to the first axis passes through the major face; and the cutting insert has a symmetry defined by a rotation of 180°
around the second axis plus a 90° rotation around the first axis.
11. The cutting insert according to claim 8, wherein:

a second axis (B) perpendicular to the first axis passes through the major face; and the cutting insert has a symmetry defined by a rotation of 180°
around the second axis plus a 90° rotation around the first axis.
12. The cutting insert according to claim 11, wherein each peripheral edge comprises at least one support edge located opposite a given cutting edge in the direction of the first axis.
13. The cutting insert according to claim 8, wherein an identical internal obtuse angle is formed between each minor face and adjacent major face.
14. The cutting insert according to claim 8, wherein each minor edge has a second section extending from the first section generally away from the opposing end surface, the second section not being associated with the minor face.
15. A turning tool comprising a cutting insert according to claim 8, the cutting insert having an operative cutting edge when seated in the turning tool.
16. The turning tool according to claim 15 in combination with a workpiece that is rotating along a longitudinal axis, the turning tool being configured to machine the workpiece, wherein:

a minor edge adjacent the operative cutting edge serves as an operative minor edge;

the operative minor edge has an associated operative minor face; and a gap is present between the operative minor face and the workpiece.
17. The turning tool according to claim 16, configured to machine a face of a rotating workpiece along a longitudinal feed direction, wherein:

the operative minor face faces a direction perpendicular to the longitudinal feed direction.
18. The turning tool according to claim 16, configured to machine a face of a rotating workpiece along a radial feed direction, wherein:

the operative minor face faces a direction perpendicular to the radial feed direction.
