    摘要： The present invention relates to a cutting insert for chip removing machining, preferably for turning. The cutting insert (10') has a substantially circular cutting edge (14') formed at a transition between an upper side (11') and an edge surface of the cutting insert. The upper side (11') comprises a chip surface (15') comprising at least one chip breaker portion (18') and said edge surface constituting a clearance surface (13') . having means (20') for indexing the cutting insert. The chip breaker portion (18') is provided at varying distance from the associated cutting edge (14'). The means (20') is provided in a position relative to a reference line or axis of the tool in order to orient the chip breaker portion (18') in the chip surface (15') to a desired position.

    摘要： The present invention relates to a cutting insert, a cutting tool for chip removing machining, a shim as well as a method for mounting a cutting insert. The cutting tool comprises a holder (31) equipped with at least one insert pocket (32) including a base surface (33), at least one circular shim (21) including opposite first and second surfaces, and at least one cutting insert (10), which comprises a circular cutting edge (14) formed at a transition between an upper side (11) and an edge surface (13) of the cutting insert. The upper side (11) comprises a chip surface comprising at least one chip breaker portion (18) and said edge surface constitutes a clearance surface. The shim (21) is provided between the base surface (33) of the insert pocket and the cutting insert (10). The cutting tool (30) comprises means for holding its parts together. The chip breaker portion (18) is provided at varying distance from the associated cutting edge (14). The shim (21) and the cutting insert (10) comprise at least one pair of cooperating projection and recess for indexing of the cutting insert. Said pair of cooperating projection and recess is provided to be positioned in a position relative to a reference line or axis of the tool (CL2) in order to orient the chip breaker portion (18) in the chip surface to a desired relative position. The number of chip breaker portions (18A-18E) is a multiple of the number of projections or recesses (20A-20E).

    摘要： A cutting tool (10) has at least one insert receiving pocket (16) with a cutting insert (14) retained therein. The insert receiving pocket (16) has a base wall (22) and a side wall (24) transversely directed to the base wall (22) with a circular recess (26) having a peripheral wall (30) extending downwardly from the base wall (22). A threaded bore (32) extends downwardly from the lower wall (28) of the recess (26). The cutting insert (14) has an upper surface (46), a lower surface (48) and a cylindrical protrusion (52) having peripheral surface (56) extending downwardly from the lower surface (54). A through bore (57) extends through the cutting (14) insert from the upper surface (46). A retaining screw (34) passes through the through bore (57) and threadingly engages the threaded bore (32) with the peripheral surface (56) abutting the peripheral wall (30) and with the lower surface (48) abutting the base wall (22).

    摘要： A cutting insert (10) has an upper surface (12) bounded by a cutting edge (14), a base (16), and a peripheral flank surface (18). The shape of the peripheral flank surface (18) varies along the height of the cutting insert (10). Near the top of the peripheral flank surface, it conforms to round or polygonal geometry of the cutting edge (14) so as to provide support for the cutting edge. Lower down the cutting insert (10), the peripheral flank surface (18) is shaped to provide transverse bearing surfaces (38) which have considerably lower pressure angles, i.e., resistance to turning moments, than would be provided by the inherent geometry of the cutting edge. Preferably, these transverse bearing surfaces (38) are formed by recessed features such as channels (40, 42), and most preferably, as chevron-type channels.

    摘要： The present invention relates to a cutting tool preferably for milling. The tool comprises a holder (30) and a cutting insert (10). The cutting insert (10) has a generally circular basic shape and includes at least one cutting edge (16) created by the transition between an upper face (11) and an edge face (13) of the cutting insert (10). The upper face (11) is a rake face, and the edge face (13) is a clearance face. The holder and cutting insert have first means (37, 13b) for preventing rotation of the insert about a center axis (20). The clearance face is conical and converges towards a lower face of the insert. The first means for preventing rotation is provided distant from and radially short of the clearance face and at a part of the insert that is closer to the lower face than to the upper face so as to constitute an indication of fracture radially inside the conical clearance face. The holder and insert comprise second means (35, 13a) for preventing rotation of the insert. Also, said step constitutes an indication of fracture, and thereby a breakage of the cutting edge is better controlled. The present invention further relates to a cutting insert and a method for preventing rotation of the cutting insert about its center axis in a holder for chip forming machining.
