MASS BALANCING DRILL BIT DESIGN METHODS AND MANUFACTURING

摘要

One disclosed method includes generating a design model for a drill bit, the design model including one or more blades and channels, determining a rotational axis of the design model, dividing the design model into a plurality of unitary volume parallelepipedic elements distributed over at least a portion of the design model, determining a material density and mass of each unitary volume parallelepipedic element and using the material density and mass of each unitary volume parallelepipedic element to calculate a total mass of the design model, calculating a location of an inertia axis of the design model, determining a resulting centrifugal force of the design model upon applying a given angular velocity to the design model and using at least a portion of the total mass and the inertia axis, and modifying the design model to compensate for the resulting centrifugal force and thereby generating a modified design model.

1. A method, comprising:
generating a design model for a drill bit, the design model including one or more blades and one or more channels that are included in the drill bit; determining a rotational axis of the design model; dividing the design model into a plurality of unitary volume parallelepipedic elements distributed over at least a portion of the design model; determining a material density and mass of each unitary volume parallelepipedic element and using the material density and mass of each unitary volume parallelepipedic element to calculate a total mass of the design model; calculating a location of an inertia axis of the design model; determining a resulting centrifugal force of the design model upon applying a given angular velocity to the design model and using at least a portion of the total mass and the inertia axis; and modifying the design model to compensate for the resulting centrifugal force and thereby generating a modified design model.
