Abstract

A cutting tool made by an additive manufacturing process is disclosed. The cutting tool has an exterior surface and an enclosed interior cavity defined by one or more inwardly facing surfaces. The interior cavity may have internal supports such as a lattice or a honeycomb structure. The cutting tool may be an insert, drill or endmill with coolant holes.

Description

technical field [0001] The present invention relates to the preparation and design of metal cutting tools. Background technique [0002] Metal cutting tools are usually made of cemented tungsten carbide or another suitable material such as PCD, PcBN, high speed steel and other cermets. Cemented tungsten carbide parts are made by pressing or extruding a blend of WC, Co, and possibly other materials into a green compact shape. The green shape is then sintered to compact and fuse the powders together. Cemented carbides are metal matrix composites comprising carbides of one or more transition metals dispersed as hard particles and cemented ) in the binder. In this way, the hard particles form the dispersed phase and the binder forms the continuous phase. For use as cutting tools including, for example, turning inserts and milling inserts, cemented carbides offer an attractive combination of strength, toughness, and wear / corrosion resistance (ie, wear resistance). Among the ...
