Abstract: A method for designing a drill bit includes assigning a score to cutting element arrangements that differ based on a design parameter, comparing the scores for different arrangements, and selecting the arrangement having the preferred or optimal score. The parameter may be, for example, the number of cutting elements in an array of cutting elements on a roller cone, the number of spiral sets in an array of a cutting elements, or the pitch between adjacent cutting elements in an array.
