US Patent 11714932 Drill bit design with reduced 3D coupled vibration

A drill bit design generator uses drill bit metrics to generate drill bit designs with reduced 3D coupled vibration. The drill bit design generator generates an initial set of drill bit designs that are simulated in a deployed or artificial environment. Simulated drill bits according to the initial drill bit designs have gyroscopic sensors that detect the presence of 3D coupled vibration. A drill bit simulator tracks metrics such as side cutting efficiency and drilling efficiency during simulations and correlates these metrics with 3D coupled vibration. The drill bit design generator determines thresholds for these metrics using correlations with 3D coupled vibration and generates updated/new drill bit designs using the metric thresholds.
