  • Publication number: 20220234151
    Abstract: The method for forming cutters includes applying a protective layer on an O-ring so as to form a protected O-ring. The protected O-ring is placed around a cutter body having a substrate section and diamond section with a metallic binder. The method includes inserting the cutter body into the pod cavity and leaching the metallic binder through an end portion of the diamond section for at least one day at 60 degrees Celsius or higher so as to form a polycrystalline diamond compact cutter from the cutter body. The protected O-ring seals the substrate section during the step of leaching. The step of leaching forms an exposed O-ring from the protected O-ring with a hardness reduction and a modulus reduction that identifies a time window for maintaining a sealing force to protect the substrate, while achieving the target profile of the diamond table for a high quality and reliable cutter.

  • Publication number: 20220162915
    Abstract: The force modulation system for a drill bit includes a cutter, a holder, a holder retention device, and a first force member made of a first woven material. The cutter fits in the holder, and the holder fits in the drill bit. The holder retention device exerts a holder retention force in a first direction. The first force member exerts a first force in a second direction. The second direction is angled offset to the first direction so as that a cutting profile of the force modulation system is variable. There can also be a second force member of a second woven material to exert a second force in the first direction for more variability of the cutting profile in the first direction. The second force member can be made integral with the first force member, including the first woven material and the second woven material being the same material.
