    摘要: Diamond bonded construction comprise a diamond body attached to a support. In one embodiment, an initial substrate used to sinter the body is interposed between the body and support, and is thinned to less than 5 times the body thickness, or to less than the body thickness, prior to attachment to the support to relieve stress in the body. In another embodiment, the substrate is removed after sintering, and the body is attached to the support. The support has a material construction different from that of the initial substrate, wherein the initial substrate is selected for infiltration and the support for end use properties. The substrate and support include a hard material with a volume content that may be the same or different. Interfaces between the body, substrate, and/or support may be nonplanar. The body may be thermally stable, and may include a replacement material disposed therein.

    摘要: A method for designing a drill bit including selecting a characteristic associated with a failure mode. A first value of the characteristic of a first cutting element and a second value for the characteristic of a second cutting element are determined. The method also includes determining whether a difference between the first value and the second value is within a predetermined range. A cutting element design parameter for the first cutting element is adjusted if the difference is outside the predetermined range. The determining first and second values, determining the difference, and adjusting a cutting element design parameter are repeated until the difference is within the predetermined range.
