    • 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.
    • 一种用于制造钻孔工具的方法和系统,包括将工具放置在系统的定位器中,然后通过执行其上的多个处理步骤使工具与模型一致。 定位器可以将刀具移动到两轴。 系统可以包括执行每个处理步骤的操纵器。 或者,系统可以包括多个操纵器,每个操纵器执行不同的一个处理步骤。 处理步骤可以包括各种成型,清洁,涂装和包装步骤。 可以在不从定位器移除工具的情况下执行处理步骤。 可以在处理步骤期间或处理步骤期间在定位器中重新定位该工具。 例如,执行处理步骤可以包括执行一个或多个处理步骤,重新定位定位器中的工具,以及重新执行一个或多个处理步骤。

    • Earth-boring tools include one or more cutting elements having at least one grading feature positioned a known distance from an initial working surface of the cutting element. Methods of grading cutting element loss on earth-boring tools include comparing locations of wear surfaces on cutting elements to locations of one or more grading features in or on the cutting elements. In some embodiments, a cutting element may comprise an insert having a generally cylindrical body, a substantially planar cutting face surface, a substantially arcuate side surface, and at least one grading feature. In additional embodiments, a cutting element may comprise a tooth having one or more grading features.
    • 钻孔工具包括一个或多个切割元件,其具有至少一个分级特征,该切割元件位于距切割元件的初始工作表面已知距离处。 在钻孔工具上分级切割元件损失的方法包括将切割元件上的磨损表面的位置与切割元件中或切割元件上的一个或多个分级特征的位置进行比较。 在一些实施例中,切割元件可以包括具有大致圆柱形主体,基本上平面的切割面表面,基本上弓形的侧表面以及至少一个分级特征的插入件。 在另外的实施例中,切割元件可以包括具有一个或多个分级特征的齿。
