Abstract
In one example, a method of designing a drill bit comprises obtaining a baseline orientation of a shaped cutter with respect to a bit body. The shaped cutter includes a shaped cutting element secured to a substrate. The baseline orientation is defined, at least in part, with respect to an rotational position of the shaped cutting element about a longitudinal axis of the shaped cutter. A wear imbalance is determined between opposing portions of the shaped cutting element at the baseline orientation. An adjusted orientation of the shaped cutter is generated having a different rotational position of the shaped cutting element about the cutter axis expected to reduce the wear imbalance.
