US 7693695 B2Abstract
θ bit = ∑ i Δθ bit , i , 412. Δθbit,i may be set equal to 3 degrees, for example. In other implementations, Δθbit,i, may be a function of time or may be calculated for each given time step. The new location of each of the cutters is then calculated, 414, based on the known incremental rotation of the bit, Δθbit,i, and the known previous location of each of the cutters on the bit. At this step, 414, the new cutter locations only reflect the change in the cutter locations based on the incremental rotation of the bit. The newly rotated location of the cutters can be determined by geometric calculations known in the art.
