摘要： A cutting insert incorporates a pre-formed discrete cutting tip which wraps around a curved cutting corner of the insert. The cutting tip includes a top layer and a bottom layer made of a relatively harder material than the top layer. In one embodiment, the bottom layer is made of polycrystalline diamond (PCD) or a polycrystalline cubic boron nitride (CBN) material and the top layer is made of cemented carbide. The cutting insert may further incorporate a chip control structure formed in the cutting tip including a plurality of facets formed on each side of a centerline for providing chip control during a cutting operation. The chip control structure can be formed in a two-step process to expose a portion of the bottom layer. The discrete cutting tip can be brazed to the cutting insert prior to forming the chip control structure.
