摘要： An indexable cutting insert has opposing upper and lower end surfaces, and a peripheral surface including three side surfaces circumferentially alternating with three corner surfaces. The three side surfaces define an imaginary triangle and an imaginary hexagon. Each corner surface intersects the upper end surface to form an upper corner peripheral edge having a primary cutting edge. In a top view, each triangle side traverses two upper corner peripheral edges, imaginary lines tangential to the end points of each primary cutting edge are either collinear or form an obtuse angle greater than 175 degrees, each primary cutting edge has a primary length greater than half the hexagon side length, and at least one triangle side traverses each primary cutting edge. The insert is removably secured in a rotary cutting tool such that one of the upper corner peripheral edges contains an axially forwardmost point of the insert's upper peripheral edge.

摘要： An indexable milling or drilling insert having a 180-degree rotational symmetry about each of the first, second and third axes (X, Y, Z) of a three-dimensional euclidean space. The insert has opposite first and second main surfaces and a peripheral surface extending therebetween. Each main surface has a main abutment surface and at least two rake surfaces. The insert has a through clamping bore which extends along the third axis and opens out to the main surfaces. The peripheral surface has two opposite front surfaces connected to two opposite side surfaces. Each front surface has a pair of outward abutment surfaces and each side surface has a pair of at least partially planar inward abutment surfaces. Each pair of outward abutment surfaces converge outwardly away from the third axis and each pair of inward abutment surfaces converge inwardly towards the third axis.

摘要： A cutting insert has opposing upper and lower surfaces interconnected by a peripheral side surface, an insert axis passing through the upper and lower surfaces, and first and second upper cutting edges formed at the intersection of the upper surface and the peripheral side surface. A lower central protuberance having first, second, third and fourth abutment walls extends downwardly from the lower surface. In a cross-section taken in a first horizontal plane perpendicular to the insert axis and intersecting the lower central protuberance, the first, second, third and fourth abutment walls define an imaginary quadrilateral having diagonally opposing first and third internal angles and diagonally opposing second and fourth internal angles. The first and third internal angles are equal to each other, and the second and fourth internal angles are not equal to each other. Two cutting inserts are removably secured in a rotary cutting tool.

摘要： An indexable cutting insert has opposing upper and lower end surfaces, and a peripheral surface including three side surfaces and three corner surfaces. Each corner surface intersects the upper end surface to form an upper cutting edge, and each side surface has a locating surface. The lower end surface has three radially outward facing lower abutment surfaces. The three locating surfaces define a first imaginary triangle having three first bisector planes and three locating planes, and the three lower abutment surfaces define a second imaginary triangle having three second bisector planes. None of the first and second bisector planes are coplanar, and each locating plane intersects two of the upper cutting edges. For each index position of the cutting insert in an insert receiving pocket of a cutting tool, one of the locating surfaces and one of the lower abutment surfaces is in contact with pocket walls thereof.

摘要： A cutting insert for retention in a rotating cutting tool having an axis of rotation has two opposing end surfaces and a peripheral 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 consisting of 2, 3 and 4. A peripheral cutting edge is formed at the junction between each end surface and the peripheral surface, the peripheral cutting edge having 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 are not aligned in an end view of the cutting insert along the first axis of symmetry.
