Abstract
The force modulation system for a drill bit includes a cutter, a blade cap, a cap retention device, and a first force member. The cutter or cutters fit in the blade cap, and the blade cap fits to the drill bit. The cap retention device exerts a cap retention force in a first direction. The first force member exerts a first force in a second direction. The cutting profile of the force modulation system is now variable in more than one direction so as to avoid excessive forces from more than one direction for each cutter on the blade cap. There can also be a second force member to exert a second force in the first direction for more variability of the cutting profile in the first direction and a third force member to exert a third force in an opposite second direction.
