    摘要： Methods for forming fixed-cutter earth-boring drill bits include retrieving a forged steel drill bit body from an inventory of substantially identical forged steel drill bit bodies including fixed blades and junk slots between the fixed blades. Cutter pockets are formed in the blades. Nozzle holes are formed in the drill bit body to provide fluid communication from an interior of the forged steel drill bit body to the junk slots. Additional methods include forging first and second steel drill bit bodies substantially identical in shape and configuration, forming first cutter pockets in the first steel drill bit body in a first configuration, and forming second cutter pockets in the second steel drill bit body in a second, different configuration.

    摘要： A method of forming at least a portion of an earth-boring tool includes entering an electronic representation of at least one geometric feature of at least a component of an earth-boring tool in a computer system including memory and a processor, the computer system operatively connected to a multi-axis positioning system, a direct metal deposition tool, and a material removal tool. The processor generates a tool path for the direct metal deposition tool. The tool path is based at least in part on the electronic representation of the at least one geometric feature of the at least a component of the earth-boring tool. The direct metal deposition tool is operated along the tool path to deposit metal on an earth-boring tool component coupled to the multi-axis positioning system to at least partially fonn the at least one geometric feature of the earth-boring tool. Methods also include methods of repairing earth-boring tools.

    摘要： In some embodiments, systems for creating and heat-treating 3D-printed objects may include a 3D printer configured to create the object. A heat-treatment apparatus may be operatively connected to the 3D printer. The heat-treatment apparatus may be configured to expose the object to an elevated temperature to heat-treat the object. A pressure-transmission medium of the heat-treatment apparatus may be configured to apply pressure to the object during heat treatment. The 3D printer and heat-treatment apparatus may be incorporated into a unified process flow volume. Methods of creating and heat-treating 3D-printed objects may involve creating an object utilizing a 3D printer. The object may be moved from the 3D printer to a heat-treatment apparatus. The object may be exposed to an elevated temperature and pressure may be applied to the object utilizing a pressure-transmission medium of the heat-treatment apparatus. The 3D printer and heat-treatment apparatus may in a unified process flow volume.

    摘要： A method of forming an earth-boring tool includes forming a tool body including at least one inverted cutting element pocket, at least a portion of the at least one inverted cutting element pocket having a profile substantially matching a profile of an actual cutting element to be secured within a cutting element pocket to be formed by subsequently machining the at least one inverted cutting element pocket. Hardfacing material may be applied to portions of the tool body. The actual cutting element pocket is formed by removing material of the tool body within the at least one inverted cutting element pocket subsequent to applying the hardfacing material to portions of the tool body. A cutting element is affixed within the actual cutting element pocket.
