摘要： The invention relates to a cutting insert having a polygonal upper side. Cutting edges, which are alternately configured as roughing cutting edges and finishing cutting edges, are provided at the edges of the upper side. The finishing cutting edges define an incircle (K1) having a diameter that is enlarged in comparison to a nominal size of the cutting insert, and the roughing cutting edges define an incircle (K2) having a diameter that is reduced in comparison to the nominal size of the cutting insert. The invention further relates to a cutting tool having a tool body on which at least one such cutting insert is disposed.

摘要： A cutting insert, a cutting tool and method of manufacturing a machined product. The cutting insert includes: upper and lower surfaces; a side surface; a cutting edge; and a rake portion on the upper surface. The cutting edge includes major and minor cutting edges that are convex toward outside of the main body portion. The minor cutting edge has a curvature radius smaller than a curvature radius of the major cutting edge. The rake portion is inclined and approaches the lower surface as moving from the major cutting edge toward inside of the main body portion and is located along the major cutting edge. An inclination angle of the rake portion becomes smaller as moving from a part continuous with one end of the major cutting edge toward a part continuous with center of the major cutting edge.

摘要： 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 (C2). 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.

摘要： An insert is disclosed for use in cutting tool applications having two major faces and at least two cutting edges. The insert is indexable by repositioning the cutting insert from one face to the other face. The inserts may be mounted in a seat formed in a fixed cutting tool. The seat has a major seating surface for mounting the insert and for receiving a retainer at a predetermined angle. In one form, the seat may also have dovetail walls oriented to engage side walls of the insert and to reduce the shear force against the retainer during contact between the insert and a rotating workpiece. The fixed tool has reliefs and a tip pocket to protect an unused cutting edge on the insert.

摘要： A tangential cutting insert has an insert body provided with a convex upper surface, a bottom surface provided with a cylindrical insert protrusion, and a peripheral side surface including a pair of opposing major side surfaces and a pair of opposing minor side surfaces. A sloped, major cutting edge in formed at the intersection of each major side surface with the top surface, the rake surface being formed in the major side surface. The bottom surface is provided with an insert protrusion abutment surface for seating the cutting insert. An insert recess is formed in the cylindrical insert protrusion, and this recess communicates with the insert's through bore. The cutting insert is seated in an insert pocket with the insert protrusion abutment surface in abutment with the pocket case. A cylindrical pocket protrusion rising from the pocket base and having a threaded bore formed therein enters the recess and is aligned with the insert's through bore. This allows the threads of a clamping screw to engage complementary threads formed in the threaded bore at a point that is close to the through bore.

摘要： A replaceable-blade cutting insert for corner milling cutters has a first and second surface; a third and fourth surface connected to a first side edge and a second side edge thereof respectively; and a fifth and sixth surface connected to a first edge and a second edge of the first surface and the second surface respectively. The first surface is used as rake face, the third surface is used as an outer perimeter flank face, and the fifth surface is used as a forward flank face. A twisted surface is disposed on a section of the third surface, forming a ridge line that acts as a main cutting edge intersecting with the first surface and interposed between the third and first surface. The first and second surface can be positioned with a height offset relative to each other so that at least one set of diagonal corners are projected.

摘要： A tool for chip removing machining, including a basic body and a cutting insert detachably connected to the basic body via an interface. The interface includes a first connecting surface formed in the basic body in which a chute is formed that has two side-flank surfaces diverging from a bottom. The interface also includes a second connecting surface formed in the cutting insert in which there are formed a number of male members having converging side-flank surfaces that abut against the side-flank surfaces of the chute, and at least one transverse shoulder surface that abuts against a transverse stop surface in the connecting surface of the basic body. When at least one first male member in the connecting surface of the cutting insert is in engagement with the chute and has flank contact with the side-flank surfaces of the chute, a lower bearing surface of a second male member laterally spaced-apart from the first male member abuts against a support surface located in the connecting surface of the basic body and spaced-apart from the chute.

摘要： A throw-away insert includes: an upper and bottom surface; two side surfaces; two end surfaces; a main cutting section formed from a ridge line positioned at the intersection between the side surfaces and the upper surface; a secondary cutting section formed from a ridge line positioned at the intersection between the end surfaces and the upper surface; an axial support surface supported by an insert pocket of a cutter body; and noses formed at the comers of the upper surface. The corner angles of the noses when seen from above are essentially right angles. The axial support surface is formed as a section of the end surface. The secondary cutting section is parallel to the ridge line at the upper end of the axial support surface and the bottom surface. The upper end of the axial support surface is positioned so that it is projected more in the direction of the longitudinal axis of the main cutting section than the ridge line of the upper end.
