摘要： A modular cutting tool assembly includes a tool holder (50) having at least one insert receiving pocket (52), and first (10, 80) and second cutting inserts (100, 102) alternately receivable within the pocket (52). The first cutting insert (10, 80) has a peripheral flank surface (18) configured to provide abutment features with mxn-fold rotational symmetry about the insert's central axis so that it can be restrained against the lateral support surfaces (56, 58, 60) in any of mxn angular positions, for at least one value of each of n and m where n is greater or equal to 3 and m is greater or equal to 2. The second cutting insert (100, 102) has a peripheral flank surface (110) configured to provide reduced-symmetry abutment features with only n-fold rotational symmetry so that the second cutting insert can be restrained against the lateral support surfaces in only n angular positions. The peripheral flank surface (18, 110) of at least the first cutting insert is configured such that a lower cross section taken through the lower part of the first cutting insert perpendicular to the central axis has a recessed form.

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.

摘要： A positioning section 16 that positions a cutting edge, used in cutting, at an indexed point is provided at a portion of a round insert 10 towards a bottom surface at a periphery of the round insert 10. A support seat 3, provided at a tool body 1, includes a first seat side surface 3b, a second seat side surface 3c, and a restraining section 5. The first seat side surface 3b and the second seat side surface 3c contact and support side surfaces of the round insert that are disposed 90 degrees apart from each other. The positioning section 16 is fitted to the restraining section 5 by bumpy portion fitting. Only one restraining section 5 is provided. A second relief portion 7 that is larger than a first relief portion 6 is provided at a corner at a side of the second seat side surface 3c.

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.
