| A high-speed milling cutter has a tool parent body and one or more plate-shaped cutting inserts with a convex, approximately arc-shaped cutting edge. The insert(s) is/are fastened in an insert seat of the tool parent body. Mating elements with mutual contact surfaces for absorbing the centrifugal forces occurring during use are provided in each case between insert seat and cutting insert. The contact surface of the first mating element is designed in the shape of a circular arc, approximately concentrically to the cutting edge. The contact surface of the second mating element is likewise designed in the shape of a circular arc, approximately concentrically to the cutting edge, or consists of at least two contact zones which lie on an imaginary circular arc, approximately concentrically to the cutting edge, the contact surface or the imaginary circular arc coinciding with the contact surface of the first mating element. | ||||||

| 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. | ||||||

| A cutting insert (22) of a trigonal shape. The cutting insert has a peripheral surface (34) that extends between two opposing identical end surfaces (28). A median plane (M) bisects the cutting insert between the end surfaces. A through bore (36) extends between the end surfaces.

Each cutting section is located between two vertexes (38) of the trigonal shape. Each cutting section has a convex primary cutting edge (42) and a concave secondary cutting edge (44) that merge together. An insert tangential abutment surface (50) is located between the cutting edge and the through bore. A primary relief surface (52) forms an insert internal obtuse angle (?) with a first reference plane (P1). A secondary relief surface (54) forms an insert internal acute angle (?) with a second reference plane (P2). | ||||||
