Abstract
The method involves providing a tool with a geometrically defined cutting edge, particularly cutting insert (1), and separating and selective forming a workpiece surface in a machining operation with the tool under formation of a nanocrystalline edge layer of the workpiece surface with a reshape smoothing process of the workpiece surface in a cutting direction of the tool. A surface roughness of the workpiece is provided in a range from 1 micrometer to 2 micrometer. An independent claim is included for a tool provided with tool cutting geometry.
