摘要： A method including of manufacturing a drill bit includes inputting bit characteristics into a simulator. The bit characteristics may include a drill bit mass, coordinates of the bit center of gravity, and an inertia tensor of the bit. The bit center of gravity and a vector of the inertia tensor may be aligned with a bit axis in the simulator. Based on the alignment of the center of gravity and the inertia tensor with the bit axis, new bit characteristics may be determined. A drill bit with the new bit characteristics may be produced.
