    Abstract: A ballnose cutting insert has a top face, a bottom face, a plurality of side clearance faces, a first nose corner, a second nose corner, and a first elongate cutting edge at the top face, a second elongate cutting edge at the top face, and a fastener bore with a center. There is a first open-end notch below the first nose corner, and a second open-end notch below the second nose corner. The first open-end notch is defined at least in part by a first generally planar engaging surface, and the second open-end notch is defined at least in part by a second generally planar engaging surface. The first generally planar engaging surface is disposed at a disposition angle relative to the second engaging surface, and the disposition angle is not equal to zero degrees. The first generally planar engaging surface is disposed from the center of the fastener bore a first abutment distance as measured along a line perpendicular to the first generally planar engaging surface. The second generally planar engaging surface is disposed from the center of the fastener bore a second abutment distance as measured along a line perpendicular to the second generally planar engaging surface. The first abutment distance is equal to the second abutment distance.

    Abstract: A cutting insert for milling operations, such as, face milling, slot milling, plunge milling, and ramping operations. The cutting insert exhibits a combination of favorable cutting edge strength, and unique cutting edge geometry, thus, allowing milling operations at relatively high feed rates. The cutting insert includes at least four cutting edges, wherein at least one of the cutting edges is a convex cutting edge. Certain embodiments of square cutting inserts will have four convex cutting edges which may be connected by nose corners. The convex cutting edge may comprise at least one of a circular arc, a portion of an ellipse, a portion of a parabola, a multi-segment spline curve, a straight line, or combinations of these. Wherein the convex cutting edge comprises a circular arc, the circular arc may have a radius greater than or equal to two times a radius of the largest circle that may be inscribed on the top surface.

    Abstract: A double-sided cutting insert may generally comprise a top surface, a bottom surface, at least one side surface interconnecting the top surface and the bottom surface and forming at least one cutting edge, a through hole extending between the top surface and bottom surface, wherein each of the top surface and bottom surface comprise at least one anti-rotation element. The cutting insert may comprise a single anti-rotation element on the top surface and a single anti-rotation element on the bottom surface. The anti-rotation element may be proximate to the through hole. A cutting tool using the cutting inserts, as well as methods of making and using the same are also described.
