摘要： Geometric compensation techniques are used to improve the accuracy by which features may be located on drill bits formed using particle compaction and sintering processes. In some embodiments, a positional error to be exhibited by at least one feature in a less than fully sintered bit body upon fully sintering the bit body is predicted and the at least one feature is formed on the less than fully sintered bit body at a location at least partially determined by the predicted positional error. In other embodiments, bit bodies of earth-boring rotary drill bits are designed to include a design drilling profile and a less than fully sintered bit body is formed including a drilling profile having a shape differing from a shape of the design drilling profile. Less than fully sintered bit bodies of earth-boring rotary drill bits are formed using such methods.
