Abstract: A cutting insert for chip removing machining of workpieces, including at least one chip-removal surface that carries away chips, at least one side surface that is a clearance surface, and at least one cutting edge formed between the at least one chip-removal surface and the at least one side surface. The cutting edge includes a main-edge segment that carries out a major part of a chip-removing operation, and a wiping-edge segment that, in the chip-removing operation, wipes off and levels a machined surface of the workpiece. The wiping-edge segment forms a depression.

Abstract: A turning insert includes a chip-breaking surface and first and second clearance surfaces located at a corner of the insert. First and second edges are formed at a junction of the chip-breaking surface and the first and second clearance surfaces, respectively. The first edge defines a major cutting edge, and the second edge defines a finishing cutting edge. The major cutting edge is straight and transforms into the second edge by a sharp transition.

Abstract: A cutting insert, intended for chip removing machining, includes a body delimited by two opposite, first and second surfaces, which in the operative state of the cutting insert form an actively chip removing top surface and a bottom surface, respectively. The insert also includes at least one side surface, serving as a flank surface, which extends between the first and second surfaces. A cutting edge is formed between the flank surface and at least one of said first and second surfaces, in which a segment is included, which has the purpose of smoothening and facing the machined surface of the workpiece. The smoothening edge segment is divided into at least three different part edge segments, a first of which forms a tangent point and is surrounded by two part edge segments having longer radii (R22, R23) than the first edge part segment.

Abstract: A turning insert includes at least one cutting surface having at least one corner area. The corner area defines a nose angle in the range of 30-85°. The corner area includes a beveled edge. A bisector of the nose angle intersects the beveled edge at a center thereof at a right angle.

Abstract: A cutting insert, intended for chip removing machining includes a cutting geometry surface having a cutting edge from which extends a primary chamfer that transforms into a chip removing surface. The chip removing surface is inclined in a inwards/downwards direction in order to permit sinking of a chip being formed, and transforms into a deflection surface arranged to initiate deflection of the chip from the cutting insert. The angle of inclination of the chip removing surface does not exceed 18°. The level difference in elevation between the primary chamfer and the chip deflection surface amounts to maximally 0.20 mm.
