Drill bit design using neural networks

摘要

The present invention is a method and apparatus which accurately predicts one or more operating characteristics of an earth boring drill bit operated under a set of known operating conditions. A range of operating conditions may be input so that the operating characteristic(s) of the drill bit may be predicted over, and perhaps beyond the range the drill bit designer has anticipated. In this manner, a new drill bit design may be refined and/or proven with a high level of confidence prior to manufacture. Only minimal field testing of the new design is required to verify its performance. <IMAGE>
