摘要： A rock formation drill bit assembly with electrodes includes a drill bit including a hollow portion that extends along a longitudinal axis of the drill bit. The hollow portion extends from a first end to a second end opposing the first end. Cutters as positioned on the first end. The cutters are configured to cut the rock formation resulting in a rock core protruding from the rock formation into the hollow portion. The rock core includes a circumferential surface. Multiple electrodes are positioned within an inner circumferential surface of the hollow portion. The multiple electrodes are configured to apply electrical discharge across multiple locations on the circumferential surface of the rock core. The electrical discharge causes the rock core to fracture.

摘要： A force stacking assembly for use with an earth boring system that includes a series of actuators that each generate a force, and that are arranged to create a combined force that is cumulative of all of the actuators. The actuators include members that react in response to an applied stimulus, such as from an electrical current or magnetic field. The members are arranged in series in a hollow housing, planar bulkheads are transversely mounted in the housing. Each of the members have an end axially abutting a corresponding bulkhead. Ends of each member distal from it corresponding bulkhead couple to a ram member, that in turn couples to a drill bit. Energizing the members causes each to exert a force against the ram member, which is transferred to the bit.
