Method of Designing and Optimizing Fixed Cutter Drill Bits Using Dynamic Cutter Velocity, Displacement, Forces and Work. March 29, 2018: US20180088552-A1

A method includes simulating a cutting tool drilling an earth formation by incrementally rotating the cutting tool at a plurality of time intervals, determining a true trajectory of a cutting element disposed on the cutting tool for the duration of the plurality of time intervals, and determining a ...
