Round cutting insert with a serrated topography

摘要

A cutting insert with a toothed topography has an upper surface, which terminates in a circular cutting edge, a lower surface and a frustoconical side wall, the the upper surface and the lower surface connects to one another, and a plurality of teeth on the upper surface, which are arranged uniformly around the circular cutting edge and extending from the cutting edge extend radially inwardly in such a way that a bisector through each set of teeth by means of a central axis of the cutting insert is. The plurality of sets of teeth in a cutting tool are arranged in such a way that a regenerative chatter is reduced during a cutting operation. A method for reducing of regenerative rattling by placing of the cutting inserts in a cutting tool to specific type and manner is likewise disclosed.
