Methods of designing a single cone roller cone bit, and bits made using
those methods are disclosed. In particular, methods of graphically
displaying a single cone roller cone bit interacting with a formation is
shown. In one method, a value of at least one design parameter for the
single cone roller cone drill bit according to the graphical display is
adjusted. The simulating, displaying and adjusting to change a simulated
performance of the single cone roller cone drill bit may be repeated as
necessary.
