Abstract:
1. A method for optimizing drilling performance of a rotary drill tool, the method comprising: securing a rotary drill tool to an orienting member; identifying a cutting element rotational axis of the rotary drill tool; measuring radial locations of a plurality of surface regions of the rotary drill tool relative to the cutting element rotational axis; identifying two or more surface regions from the plurality of measured surface regions; determining a best-fit diameter substantially intersecting the two or more identified surface regions; modifying at least one selected surface region from the plurality of measured surface regions such that the at least one selected surface region is located at a selected radial distance relative to the cutting element rotational axis, wherein modifying the at least one selected surface region comprises modifying at least one of the two or more identified surface regions such that the best-fit diameter intersecting the two or more identified surface regions is substantially the same as a target diameter relative to the cutting element rotational axis.
