    摘要： Cutting elements for earth-boring tools may generate a shear lip at a wear scar thereon during cutting. A diamond table may exhibit a relatively high wear resistance, and an edge of the diamond table may be chamfered, the combination of which may result in the formation of a shear lip. Cutting elements may comprise multi-layer diamond tables that result in the formation of a shear lip during cutting. Earth-boring tools include such cutting elements. Methods of forming cutting elements may include selectively designing and configuring the cutting elements to form a shear lip. Methods of cutting a formation using an earth-boring tool include cutting the formation with a cutting element on the tool, and generating a shear lip at a wear scar on the cutting element. The cutting element may be configured such that the shear lip comprises diamond material of the cutting element.

    摘要： Cutting elements providing a relatively constant superabrasive area in contact with the formation responsive to weight on bit during a substantial portion of the useful life of a circular cutting face cutting element or other cutting element exhibiting a non-linear cutting edge, for example, from about 5% diametrical wear to in excess of about 30% diametrical wear in the case of a circular cutting element, measured across the cutting face. The superabrasive table of the cutting element is configured, internally, externally, or both, to vary in depth radially and laterally, as required, so that an increase in width of the contact or wear flat area with the formation and the variation in table depth as the cutting element wears, are substantially offsetting. The rate of penetration of a drill bit so equipped may thus be maintained at a desirable magnitude without a substantial increase in weight on bit as the cutting element wears, since the superabrasive contact area is maintained relatively constant.

    摘要： An improved earth-boring bit the rolling cone variety and an insert for use therein is provided. A superabrasive element is coated with at least one layer of metallic material. The superabrasive element then is placed in a receptacle cavity in a pre-formed hard metal jacket. The superabrasive element then is brazed or infiltrated to the hard metal jacket. Metallurgical and mechanical bonds between the superabrasive element, the at least one layer of metallic material on superabrasive element, the braze or infiltrant binder material, and the fracture-tough material of the hard metal jacket retain the superabrasive element in the cavity of the hard metal jacket. Improved earth-boring bits according to this embodiment of the present invention provide abrasion-resistant earth-boring bits of the rolling cutter variety. Such improved bits, and the inserts therefore, are formed without resort to high-temperature, high-pressure processes.

    摘要： A rotary drag bit equipped with a plurality of cutters, each including a superabrasive cutting face, wherein cutters carried by the bit have at least two differing chamfer geometries adjacent their cutting edges. Chamfer geometries are selected according to location on the face of the bit responsive to the relative ease or difficulty of cutting formation rock and the severity of dynamic loading at that location. The bit face may be characterized as comprising at least two areas or regions bearing cutters having differing chamfer geometries to maximize rate of penetration of the bit while preserving cutter integrity when subjected to differing stresses and encountering zones of the formation exhibiting different strengths. Characteristics, such as hardness, abrasiveness and homogeneity, of the target formation or formations to be drilled by the bit may be considered when selecting appropriate chamfer geometries for the cutters allocated to cut each formation zone opposite the bit face.

    摘要： Methods for forming cutting elements, methods for forming polycrystalline compacts, and related polycrystalline compacts are disclosed. Grains of a hard material are subjected to a high-pressure, high-temperature process to form a polycrystalline compact. Inclusion of at least one relatively quick spike in system pressure or temperature during an otherwise plateaued temperature or pressure stage accommodates formation of inter-granular bonds between the grains. The brevity of the peak stage may avoid undesirable grain growth. Embodiments of the methods may also include at least one of oscillating at least one system condition (e.g., pressure, temperature) and subjecting the grains to ultrasonic or mechanical vibrations. A resulting polycrystalline compact may include a high density of inter-granularly bonded hard material with a minimized amount of catalyst material, and may provide improved thermal stability, wear resistance, toughness, and behavior during use of a cutting element incorporating the polycrystalline compact.
