Abstract
Methods of designing an earth-boring tool are described, including calculating one or more performance parameters of the tool based on drilling conditions, a plurality of depth of cut values, and a set of values of other design variables. Methods of enhancing a performance parameter in the design of an earth-boring tool are also described, including calculating the performance parameter based at least partially on a plurality of depth of cut values and a first set of values of other design variables, calculating the performance parameter based at least partially on a second set of values of the other design variables different than the first set, and comparing the calculated performance parameters to determine which of the first and the second set is closer to a target range or value across a range of the plurality of depths of cut. Related methods of forming an earth-boring tool are also described.
