Abstract
Official abstract text for this publication.
A cutting tool includes a polygonal cutter body and an end cutting insert for chipforming machining mounted in a serrated seat disposed at an axial end of the cutter body. A bottom surface of the insert has a plurality of parallel serrations meshing with corresponding serrations of the seat. The serrations extend transversely relative to the longitudinal axis for resisting axially rearward cutting forces applied to the insert. The seat is formed directly by the cutter body, or by a shim disposed beneath the insert. The shim is provided with a downward lip to transfer axial forces to the cutter body. The insert can be square or triangular, wherein the serrations are in the form of a plurality of sets of parallel serrations disposed adjacent respective cutting edges.
First claim
Opening claim text (preview).
What is claimed is: 1. A cutting insert for chipforming machining, comprising a polygonally shaped body including top and bottom surfaces interconnected by a pair of long side faces and a pair of short side faces; the long side faces intersecting the top surface to form therewith a pair of main cutting edges; the short side faces intersecting the top surface to form therewith a pair of secondary cutting edges; the secondary cutting edges being shorter than the main cutting edges an…
