Abstract
The multi-directional force modulation cartridge system has a modular relationship the drill bit so that the cutting profile of a cutter in the drill bit can be adjusted without requiring modification of the drill bit itself. The force modulation cartridge system includes a cutter and a cartridge. The cutter can be independently replaced due to wear or replaced when the cartridge is replaced. The cartridge includes a holder, a seat, and a cartridge force member. The cartridge can have different holders and seats adjusted for different formations and drilling conditions. The alignment of the holder and the seat is set by a holder sliding angle and a seat sliding angle with the holder sliding surface and the seat sliding surface being parallel and in sliding engagement. A seat post supports the cartridge force member to exert a restoring force according to the holder sliding angle and the seat sliding angle.
