摘要： A cutting tool has a cutting insert removably secured to a tool body by a fastening member. The cutting insert includes a clamping bore having at least two upper and at least two lower clamping portions intersecting a first and a second horizontal plane, respectively, the first and second horizontal planes being perpendicular to a central axis and spaced apart from each other, and the clamping bore being non-circular at cross-sections taken in the first and second horizontal planes. Upper and lower imaginary lines tangential to the at least two upper and the at least two lower clamping portions, respectively, form zero or acute first and second clamping angles with the central axis, the first and second clamping angles being different. Exactly two upper and exactly two lower clamping portions are in simultaneous clamping contact with an equal number of corresponding clamping zones on the fastening member.

摘要： A cutting insert for retention in a rotating cutting tool having an axis of rotation. The cutting insert comprising two opposing end surfaces and a peripheral side surface extending therebetween, each end surface having a mutual first axis of symmetry passing through the end surfaces about which each end surface has N-fold rotational symmetry for some value of N where N is chosen from the group of 2, 3 and 4. A peripheral cutting edge formed at the junction between each end surface and the peripheral side surface, the peripheral edge comprising N curved cutting edges merging with N straight cutting edges which extend between the curved cutting edges at extremities thereof. The curved cutting edges of the two end surfaces do not overlap in an end view of the cutting insert along the first axis of symmetry.

摘要： A shank of a milling cutter can be somewhat elastic. As a result, during plunging down into a workpiece the milling cutter will not plunge in a true axially downward direction and will form a slanted wall in the workpiece. A milling cutting insert (10) is provided which is capable of 'straightening out' the slanted wall (64).

摘要： A tangential cutting insert (10) has three pairs of surfaces. A first pair has upper (12) and lower (14) surfaces, a second pair has front (20) and rear surfaces, and a third pair has two side surfaces (24). The upper and lower surfaces and the side surfaces extend between the front and rear surfaces. A main cutting edge (32) is formed at the intersection of the front surface (20) with the upper surface (12). A front portion(46) of the upper surface extends rearwardly from the main cutting edge (32) and upwardly toward a central portion (48) of the upper surface (12) as seen in a side view of the cutting insert (10). The main cutting edge (32) is curved and slopes downwardly toward each of the auxiliary cutting edges (34) as seen in a front view of the cutting insert (10).

摘要： A tangential milling cutting insert (10) having two identical opposing end surfaces (12) with two identical opposing major side surfaces (18) of a generally parallelogrammatic shape and two identical opposing minor side surfaces (16) extending between them. Each end surface (12) has a peripheral edge (40) containing cutting edges (52) and four corners of which two diagonally opposed corners are lowered (24) and the other two are raised (26). Each end surface is provided with an abutment (28) member having an abutment surface. In each cross section of the cutting insert taken in a plane parallel to a minor plane of the cutting insert, the abutment surface (30) is closer to the median plane than a respective leading section of a major cutting edge (54).

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 trailing mounting portion (4) has upper, lower and side walls (12, 13) extending from the front cutting portion (2) to a rear abutment wall (14) of the trailing mounting portion (4) oriented generally co-directionally with said operative front surface (3). The side walls (13) of the trailing mounting portion (4) meet with the rear abutment wall (14) at rear edges (15). The rear abutment wall (14) comprises two lateral surfaces (20) and a central surface (22) therebetween. The lateral surfaces (20) converge from the rear edges (15) in the direction towards the front cutting portion (2), and the central surface (22) protrudes, in the direction away from the front cutting portion (2), outwardly from adjacent portions of the lateral surfaces (20) and meeting therewith at merging edge regions (23).

摘要： A cutting tool assembly (20), for example ball nose end mill, having a single replaceable cutting insert (24, 100, 106) clamped between two clamping jaws (34, 32) having clamping surfaces (50, 42) with geometries complementary to those of the clamping surfaces (66, 64) of the cutting insert. In an end view of the cutting tool assembly, the clamping surfaces (50, 42) of the clamping jaws (34, 32) are at least partially convex and the insert clamping surfaces (66, 64) are concave. The cutting insert is secured in position by means of a clamping screw (26) that passes through through bores (44, 118) in the clamping jaws and in the cutting insert. When the cutting insert is clamped between the clamping jaws the side cutting edges of the cutting insert are provided with adequate support and are accurately radially located.
