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: A cutting insert and method for machining a workpiece. The abstract of the disclosure is submitted herewith as required by 37 C.F.R. §1.72(b). As stated in 37 C.F.R. §1.72(b): A brief abstract of the technical disclosure in the specification must commence on a separate sheet, preferably following the claims, under the heading “Abstract of the Disclosure.” The purpose of the abstract is to enable the Patent and Trademark Office and the public generally to determine quickly from a cursory inspection the nature and gist of the technical disclosure. The abstract shall not be used for interpreting the scope of the claims. Therefore, any statements made relating to the abstract are not intended to limit the claims in any manner and should not be interpreted as limiting the claims in any manner.

Abstract: A method for machining an enlarged profiled bore in a workpiece utilizing a numerically controlled machine and particularly a tool comprising a boring bar rotatable and axially displaceable relative to the workpiece. The milling cutter is eccentrically mounted in the boring bar thereby facilitating radial movement of the milling cutter. The milling cutter is adapted to follow a predetermined contour during removal of the boring bar from the workpiece thereby to form a correspondingly profiled bore.
