<p>In a downhole drilling tool (100) designed to form a wellbore (30), cutting elements (60) are disposed at respective locations on exterior portions of each of a plurality of blades (131) based at least in part on a level of force balancing resulting in a cutting face profile and force balancing each respective group of three neighbor cutting elements (60) on the cutting face profile to further minimize imbalance forces associated with each respective group of three neighbor elements acting on the downhole drilling tool. A method of designing a downhole drilling tool is also disclosed.</p> |
