    摘要: A method and system for manufacturing a earth boring tool, comprising placing a tool in a positioner of an system which then conforms the tool to a model through the performance of a plurality of processing steps thereon. The positioner may move the tool in two axis. The system may include a manipulator which performs each of the processing steps. Alternatively, the system may include a plurality of manipulators, each performing a different one of the processing steps. The processing steps may include various shaping, cleaning, painting, and packaging steps. The processing steps may be performed without removing the tool from the positioner. The tool may be repositioned in the positioner during or between processing steps. For example, performing the processing steps may comprise performing one or more of the process steps, repositioning the tool in the positioner, and re-performing the one or more of the process steps.

    摘要: An earth-boring bit has at least one steel tooth with a scoop-shaped profile. The scoop-shaped profile is formed by milling and hardfacing a tooth to have at least one flank with a concave profile. Additionally, the tooth may contain one flank with a concave profile and another with a convex profile. The centerline axis of the tooth may be moved to alter the angle between the flanks and the centerline to vary the manner in which the tooth engages the formation.

    摘要: The present invention relates to a system and method for automated or “robotic” application of hardfacing to the surface of a steel-toothed cutter of a rock bit. In particular, the system incorporates a grounded adapter plate and chuck mounted to a robotic arm for grasping and manipulating a rock bit cutter beneath an electrical or photonic energy welding source, such as a plasma arc welding torch manipulated by a positioner. In this configuration, the torch is positioned substantially vertically and oscillated along a horizontal axis as the cutter is manipulated relative along a target path for the distribution of hardfacing. Moving the cutter beneath the torch allows more areas of more teeth to be overlayed, and allows superior placement for operational feedback, such as automatic positioning and parameter correction. In the preferred embodiment, sensors provide data to the control system for identification, positioning, welding program selection, and welding program correction. The control system, aided by data from the sensors, manipulates the robotically held cutter while controlling the operation and oscillation of the torch.
