    Abstract: A turning insert includes a top surface, an opposite bottom surface, side surfaces connecting the top surface and the bottom surface and two opposite nose portions. Each nose portion includes a convex nose cutting edge, a first cutting edge and a second cutting edge. The convex nose cutting edge connects the first and second cutting edges. A bisector extends equidistantly from the first and second cutting edges. In a top view the first and second cutting edges on the same nose portion form a nose angle (α) of 70-85° relative to each other. Each nose portion includes a third convex cutting edge adjacent to the first cutting edge and a fourth cutting edge adjacent to the third cutting edge. In a top view the fourth cutting edge forms an angle (β) of 0-34° relative to the bisector.

    Abstract: A turning insert includes a top surface, an opposite bottom surface, a reference plane located parallel to and between the top surface and the bottom surface, and a center axis extending perpendicular to the reference plane and intersecting the reference plane (RP), the top surface and the bottom surface. Side surfaces connect the top surface and the bottom surface. Three nose portions are formed symmetrically relative to the center axis. Each nose portion includes a first cutting edge, a second cutting edge and a convex nose cutting edge connecting the first) and second cutting edges. In a top view the first and second cutting edges on the same nose portion form a nose angle of 25-50° relative to each other. The distance from the first cutting edge to the reference plane varies in such a way that that this distance is decreasing at increasing distance from the nose cutting edge.

    Abstract: A cutting tool has an S-shaped cutting insert retained in a corresponding insert pocket. The insert pocket has a longitudinal main axis extending in a forward to rearward direction. The cutting insert has a longitudinal first axis and a lateral second axis, with two opposite cutting portions and a clamping portion therebetween, arranged along the first axis. The insert pocket includes a forward clamping portion with a forward abutment surface, and a rear clamping portion with first and second rear abutment surfaces. Two side flanks of the cutting insert extend longitudinally oppositely, with first and second clamping surfaces located adjacent each side flank. The first and second clamping surfaces adjacent one side flank abut the first and second rear abutment surfaces, respectively. The first clamping surface adjacent the other side flank abuts the forward abutment surface. Neither of the side flanks abuts the tool holder.

    Abstract: This application relates to a cutting insert and method for machining a workpiece. This application further relates to a method for the machining of a workpiece using such an indexable insert. In this case, the term “machining” means, among other things, the first-time machining and/or a re-profiling of a wheel or of a brake disc of a wheel set of a railway vehicle. An object of at least one possible embodiment of the present application is to create a cutting insert that is as economical as possible. An additional object of at least one possible embodiment of the present application is the most effective method possible and a lathe tool that is well-suited for the machining of a workpiece, such as for the copy turning and/or for the first-time machining and/or for the re-profiling of a wheel or of a brake disc of a wheel set of a railway vehicle, using a cutting insert described herein.

    Abstract: The invention relates to a reversible cutting plate made from ceramic material for chucking in a cutting tool for machining cast materials, with each corner of the reversible cutting plate (9) having a minor cutting edge (5a, 5b, 5c, 5d) and a major cutting edge (4a, 4b, 4c, 4d). In order to remove cast-material shavings from the cutting edge, it is proposed that the corners of the reversible cutting plate (9) be ground, pressed or injected into approximately null of the diagonal plane (D) and form a triangular face (3) and the triangular face (3) have at least one incline,
